I received a Swytch email stating that they are upgrading motors for those expecting the Oct 2018 batch. There is also a 1 month delivery delay as a result. Stats of the new motor: 70% less rolling resistance, 20% lighter, 25% higher torque.
Received my Swytch Brompton Pro Kit today after ordering it in Nov 2019. Will be installing and testing once this London rain stops.
How has the kit worked for you? Is it worth paying so much money?
I’m on the list for the next batch but already recently bought an eBrompton. The large bag is only a little smaller than the one I have for my M6R and carries enough to be useful. The fitment is very well designed and it’s a quality product. Doesn’t have any of the issues you get with bought in bits. Very very impressed with it. Clearly it’s a new 2020 model and the issues have been programmed out. The delivery is smooth and predictable and it doesn’t leap away if you’re manoeuvring slowly such as through gates on a cycle path. I have absolutely no complaints. The Swytch will be for my M6R 2017 bike. Will be fun to compare.

Nice review! I like that you presented the install process, step by step. Gave me a clearer image of how it will install on my Brompton. This makes me more excited to receive my Swytch. Which I just got notified that it's in production. So I should get it end of August.
Did you get yours?
@@DrJamesT Not yet. There's been customs delays for the U.S. Stricter regulations on lithium batteries being shipped. Especially imported. But I've gotten constant updates from Swytch about the process. They've even upgraded us to a newer model wheel and motor for the inconvenience.
So I finally got mine. Got everything hooked up. I love it. The only thing I have to get used to, is having weight (battery) on the handle moving with my turn and it catching on to the c bag. I thought of modifying a mount that places where the bag clip is. Maybe in the future. I have a back pack, so I can place my bag back there for now.
Excellent video showing the Brompton installation and great to know that the official Brompton luggage bags can still be used with the swytch kit. Only thing missing on the installation is the install of the brake sensors - would like to see how this is done. Looking forward to my kit arriving.
Massimo Stefani break sensor is optional. In my opinion is not needed. The motor is cut off as soon as you stop pedaling. This only works for people who stop pedaling when they break.
Break sensors: legal requirement in Europe.
I recommend to wait a little longer for their new version to come out, which is 50% lighter.
Fantastic choice no doubt about it but as with many things in life ( you can’t have everything ) a front hub motor means removing the front dynamo that powers the front and back lights and to me that is a waste of a good upgrade to my Brompton . I realize that the lights can be powered by the same battery running the hub motor but then again it is an additional load on the battery ( even if small ) . Well done swytch
Dear All, I'm in the process of installing the kit I bought. The extension bar height was 2cm too short for the old T Bag, which has the plastic handle giving a 35cm height. I could chop off the plastic handle, which is too drastic for me. Or buy the new Brompton Roll top Bag (22cm height), which doesn't have the plastic handle sticking up. The extension bar raises the battery bag 6cm in height. Shame that I needed 8cm to clear the T bag frame.
Does the swytch work well without a battery just like the Brompton Electric?
It's appealing to me that I can use it with and without the battery. But I prefer the broader ecosystem of the classic Bromptons.
Thanks for the great review. I ordered the 50 miles kit for my Brompton without the bracket (cable only) to be able to put the battery/controler in my T-bag.
How did you get the option to have the cable only option? I would much prefer putting it in my T-Bag and have a smaller controller/display on the handle bar
The cable version is limited to lucky 30 people, here's part of the kit, Panda and Swytch is own by the same person www.pandaebikes.com/shop/conversion-kits/panda-250-pro-electric-bike-kit-with-battery-36v-250w/
@@DrJamesT Sorry about the late reply. I chose it during the backer survey. I'm still afraid I would need to plug/unplug several cables each time I need to take the T bag off and fold my bike.
Do you have a guide for the secret menu?
I find the point that you have to hammer the front fork in rather disturbing; to me that says that the kit isn't _really_ optimised for the Brompton. How hard is it then to remove the front wheel when you get the inevitable puncture?
I have converted my 2 Bromptons with Bafang 1kw at about £1k per kit.
The downsides are that you lose the back fold but not the others so you can still 2/3 fold them and you need battery power to cycle (but not push or freewheel) at all times as the Nylon internal drive gear is engaged when the pedal is.....
The upsides are -
Plenty of power! (technically illegal on UK roads at present). I cycle at 15-20mph ona mid-range setting of 3-5 out of 9 and this yields 30-35 mile range.
Fairly light with motor and battery weighing in at about 4k each. The battery i use is the largest currently available at 17.5ah.
The batteries can be charged off bike and carrying one or even 2 spares is not a problem weightwise.
These motors fit any 68mm bottom bracket bike and i swap one over toa road bike or an MTB in the Winter.
I also have adapters for chainring sizes from 42-60. Rings from 54-60 really make a difference for road and light track use...
Hope this helps👍🏻
Laurie Allan please hop over to the Brompton hack Facebook group to show off your work. Love to see it!
@@DrJamesT will do👍
Laurie Allan
Any chance to post a video?
Thank you. I think I will purchase it. 4000$ for the electric Brompton is insane. Can you comment on the differences between the original and this conversion? I don't see much of a difference honestly.
Miloslav Antonov see slidingdownthehill’s comment - I agree with the differences they pointed out
Try a NANO: uses Brompton luggage system, choice of batteries (including a can-fly model) and has a Pedal First Throttle as well as cadence. Get in touch!
Do you work for Nano?
I was really keen on this system until I spoke to my local bike shop, he stopped selling them due to reliability issues, I'm wondering if they've improved this and that's why the price has risen. It would also be good to know what the waterproof rating is on the motor.
Ride On Cycling the original kit is not perfect- the mount needed conductive grease. There are many in the forum showing thousands of miles in their speedometer. I have done 500 miles. I sent it back once for a blown fuse that I can fix myself but it was still under warranty. Fix took 3 weeks. Their customer support have improved a lot. Their new battery weighs a lot less but the mount design is the same. I have ridden the bike through many london rainy days. Motor is probably the most robust part. Members are now swapping their big batteries with new smaller ones on their own for £80. It’s great for hackers / tweakers because most parts are off the shelf.
@@DrJamesT Thanks for the update, an interesting one to watch.
0:26 had me dying 😂😂😂😂😂😂
Sebastian Kaczmarek wait, what’s funny about that scene?
@@DrJamesT do u not get it ?
No
Cade Hodges read what he wrote on the little display😂😂😂😂
ha ha ...spotted that before I read the comments...well spotted
In 2021 the waiting time for this battery pack to ship to Europe is long...if money were no object, I would buy the Brompton version.
That’s what you meant to say!
Please do more review especially the sound of the motors etc please thank you and have a nice day to you
Check out the NANO: Uses standard luggage, choice of batteries, handlebar display, Pedelec, 'pedal first' throttle and Twist & Go versions. Same motor.
Check out the ARCC Brompton!
Doing the kit is better than buying the factory Brompton ebike setup?
Paco Edpalina Yes.
Just received an email that delivery date is early February for USA, U.K. and EU for batch 2 and 3. Batch 1 should have been delivered. Users can comment on this thread.
Kit / Box - arrived today .. !!
I paid more for this kit to have it sooner, finally I got it after nine months with a missing part and a range of only 20 KM with the max version,
I contacted support and they refuse to believe what you tell them and even when a fault is obvious, they continue to deny the problem, I regret buying this kit, even if the concept is great, the company is not serious.
thanks for that - i tried an e-brompton today - and it was pretty impressive to say the very least. I'm sorely tempted.. but now having seen this I've got a good comparison. The e-brompton does have a lower centre of gravity bringing stability - but you're losing the bag access which for me and i guess many - this is a big negative. Not forgetting the massive price tag and the non upgrade to e brompton offering.
slidingdownthehill if you haven’t ridden on an electric bike before, you were impressed by the feel of the motor propelling you. The e Brompton dealer claims the fork was reinforced to meet EU standards. There is a bigger bag available that hold both the battery and your own items. You can fold with the battery intact. The downer for me is lack of handle bar throttle option and acceleration configuration. The e Brompton motor accelerated pretty hard at setting 1 while I was pedaling through a tight u turn making it dangerous. Brompton took my feedback and claimed they have reconfigured it. When I presented this problem to Oliver he showed me how I can configure the acceleration myself. He had the lowest acceleration programmed in as default. Reserving the full throttle for experienced riders. He has a cyclist mindset. Whereas Brompton hired Williams Engineering, a formula 1 car company, petroheads with little experience in commuting with a bike. Brompton parts are proprietary, meaning you have to buy from them. I expect a premium price on their battery. Swytch uses mostly off the shelf parts that could be bought even when the company disappears. Sure the parts are from China but Oliver has been selling electric bikes for 5 years he knows the best value suppliers from a country that have been using electric bikes for decades.
+Big League !! thanks for the info, I experienced the shock of throttle going round a short corner in the ebrom as well, I found it for a first time ride very scary. ( they're excellent bikes , but once you've ridden one for a while control is key !!) I'm pretty well sold on the swych , the off the shelf concept makes the product pretty well future proof. I don't mind brompton doing all the dev and charging £ for it , but the lockin is somewhat more expensive. One q about swytch is the connector water proof if you have to ride without battery ? (the demo looked pretty exposed)
Yes. That’s one of those questions I asked Oliver. He chose a rust free alloy so it would be weatherproof. He said he might include a cover for further weather proofing. E Brompton chose a spring action auto shut cover, which you can see in my eBrompton review.
If you tested the E Brompton recently, your shock is evidence that their new acceleration configuration isn’t slow enough or their pedal sensor is too sensitive. Riders will have to cruise around corners. U turns will be challenging.
Big League hi there , did you see the fitting of the brake cable sensors ? It's the one thing I've yet to see done on a brompton. I've see another demo using another bike where it looks simple - but i think on a brompton that might not be the case , appreciate you only had the 'tester' for a few hours ! I dropped them an email with a few questions - alas no reply / they're busy. Also for some reason their own yt videos are 'comments disabled' , which doesn't exactly invite comments / questions ! Which i'm sure there are many !!
Does this work better with a 6 speed or 3 speed Brompton? Also does the new swytch system have no lcd display?
alpha omega if you have strong legs and arms 6 otherwise 1 speed. Correct in the new one, option is chosen by a series of LED lights
@@DrJamesT thank you. New one have a front led light?
Nice review. I'm still waiting for my Brompton Swytch Kit to arrive. I'm hoping it'll be by the end of December or the middle of January. It's been a bit frustrating getting a response from their customer service, and a lot of other backers have expressed this looking for any answers. How about you? Did you get your kit already? But it's a bit comforting to see that it actually exist. I am hoping that I didn't get scammed by some Britsh folks, but that the Brits show good faith and represent how good their company and product is. I'll be glad to brag about how good the kit is when I get it.
Dante Adela I am in the second batch, which is now delayed until mid-Jan. Only the first batch got their kit. I bought mine with AMEX, which is very good at refunding if the company doesn’t deliver. I also bought it directly through their site, so there is no middle man to dispute. The emails they send of delays is ample evidence. Their CEO stopped responding to my emails. Their announcement that they have investors now should be reassuring. However, I am not expecting that they fulfill their claim that the Brompton sized motor will also receive upgrades as their wording in the email has been vague. These motors are for niche bikes, more challenging due to smaller size. The same goes for their high performance motors as they are niche.
I’m still willing to wait as I had kickstarter products that took a whole year after it’s suggested time of delivery. It’s still the lowest priced kit I can buy. If something else comes up that offers more, I’ll be ringing AMEX.
Dante Adela regarding “they are British” although natural, is not strong objective evidence whereas investors is obtained is in gauging a business. British, German, Japanese - companies are very capable of making unethical decisions as a result of being desperate. Swytch pricing is very low and it doesn’t give him much flexibility. All he has is time. What’s different between UK vs a third world country is regulation. Ombudsman are there to help us little consumers. These rules are in place to prevent scamming. Evidence that scams have existed prior. I don’t know where Kickstarters lie in the spectrum as crowd funding is very different than buying a product direct. This is why I bought it off their website instead.
Art innovations e package is a better buy in my opinion guaranteed for 5 years so beat that!
Roger Tapley could you please post the link to the company? I can’t find it on google. Thank you.
Has it been tested for heavy rain? Especially the motor is located in the wheel hub where it is prone to corrosion, water & dust accumulation.
many in the Swytch FB community has shown it surviving heavy rain.
How would I acquire that bar extension unit? You mention that if user is contemplating the 50 mile unit with the 4Kg addition of weight, that user should test drive it first, how would the user accomplish this? Pre order is 35% off so in about 4.5 months I would receive the kit, install it, and test it out. Is the 4Kg that much of an addition to the handlebars? Is it not as safe? I really want to pull the trigger on this. It looks fantastic. Nice vid.
Extension: amzn.to/2OCnjx8 . If you are in London you can visit their factory warehouse in hackney (one seen in the video) to demo their huge variety of bikes with the kit installed. You can even bring your own bike and have it installed temporarily. Putting heavy weight on the handle bar directly changes...the handling. Not an issue for those with strong arms. If you are commuting 25 miles I would buy a second charger to leave at work. Instead of getting a bigger battery.
Thanks for subscribing Jason Palmertree. Correct me if I am wrong, this is the cheapest e brompton conversion kit in the market. The current manual also hints instructions to unlock the legal rate speed limit. No e-brompton bike kit can do this. This is for off road riding. Do so at your own risk. Ride safe.
I have to say the video which u have has a better instruction than the old man doing it in the swytch videos now I know what that strap was for and I was complaining about my battery mount tipping when I put my battery the only thing I am concerned about now is the 2 blue cable dangling out of the bottom of the battery pack they are open should I put insulation tape on it or gaffer tape to waterproof them?
Rahul Macwan are your cables different from what’s shown in the video? Because everything in the video is rain resistant
@@DrJamesT i think they are for the brake it came with 4 cables 1:wheel motor, 2: pas sensor and 3&4 is for the brakes blue colour
It came with extra blue cables for bikes that have hydraulic brakes. I just received mine a couple days ago.
I just got my switch installed! Where did you get that extra mount for the bar
I'm going to install it this week. I'll figure out if the exta mount actually works before I make an official recommendation
@@DrJamesT we look forward to it
! It is clearly impossible to use C-bag or T-bag on an M-type
Did you have success with the handlebar mount? I’m waiting for my kit order to arrive and making plans for installing when it eventually gets here. Thanks for the helpful and well presented video.
Is that the greenway near Stratford?
What gave it away?
@@DrJamesT I used to cycle through it all the time
Isn’t the tiny bafang motor best option for Brompton?
Why is it the best option?
Just any ordinary chinese e-bike kit, that collected battery and controller in fabric bag.
I have an ancheer folding 20inch I have this idea of putting 2 motors on it and this kit seems like it would work except there's no disk break how would I go about getting a disk break on there
DR.Acula Anderson there is a disc break version
Oh well that makes it easy thanks
Fixing a puncture might be problematic considering the tight fit of the front wheel during installation
Niall J Russell it took 5 mins to remove everything. Putting it together was harder
Same thought - who wants to bang a wheel back in after a flat repair! A bit of file on the front fork drop outs would help it slip in as it should - "nice & safe / snug" indeed!
Fitting Marathon Plus tyres would make that eventuality far less likely. I've ridden daily on these tyres for 4 or 5 years with only one puncture - caused by a large staple that would have punctured a tractor tyre
Are they selling bikes or only kits?
Awesome J both
@@woodenchopstick I cant find them(bikes) on their site though that's why I asked
@@ohhancil They previously has a "stay tuned" section for full ebikes. It's not on the website anymore. Swytch is about converting your current bike. If you want an electric bike designed from the ground up check out Go-Cycle
@@DrJamesT do they fold like brompton??
nano sell complete bikes or sell the kit and will fit it for a fee if you do not want to diy
I watched you video may of times bit the bullet and bought a kit, received it after having to chase them up. received fitted the kit va your video Pad disc broke so left with a broken PAD disc glued together to try and fit temp then to find out the sensor dues not work, continues emails about sending me a new pad disk and sensor one response email to apologies and no left with no idea about getting a replacement parts.
They do not respond to emails or any form of contact.
Although if you want to by a kit they will respond and take your money!!
Seems to be very lack of after care from them very socking customer service no left with a kit that dues not work.
So shocked with this company as really want this kit to work on my bike now left hopeless.
Feeling totally ripped off and left hopeless
apologies for negative on your video but left hopeless.
It's a fair comment, I've been monitoring their customer service, it's not good. Good thing is most parts are supplied by third party chinese no name companies. meaning you can purchase them cheaply on eBay. If this company goes bankrupt you can still replace a lot of the parts including the motor and battery. Here's the ebay link of the PAS Disc. Make sure the number of magnets match: www.ebay.co.uk/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=electric+pedal+assist+sensor&_sacat=0
I just received the kit myself over the weekend. 6 months wait for a kickstarter / indigogo is kit is quite quick. I haven't put it together yet.
This looks very close to the kit PAS www.ebay.co.uk/itm/Electric-Bike-12-Magnet-Easy-Fitting-Split-PAS-Pedal-Assist-Sensor-Cadence-Speed/272864678672?epid=2267919300&hash=item3f88009310:m:mGlCZvAfALNRd1OuLiOJ0vg:rk:3:pf:0
Emailed Oliver, with a response to say my complaints ware unnecessary about the lack of customer service, because they cant respond because they have real people with real jobs. (what about the people how pay a lot of money to buy there kits) told that I had to send photos and send my sensor back so they could replace it. Witch is far but now left with another wasted week or so they can replace. opt to just buy the sensor on ebay. Glad am not the only one how thinks there customer service is not good. Thanks for the ebay link... @@DrJamesT
What baffles me about the 'official e-brompton' is how long they are taking to release it (still not available in US early 2019) and that it only goes 15MPH.
are vee yup I totally agree and I think it’s to do with safety regulations. They claim to upgrade the fork and had it tested to ensure it can support the weight of the average American jumping off a curb.
The 15mph is so that the bike is compliant for the EU, they are a British make.
Is this kit only compatible with the Brompton foldable bikes?
It's for all kinds of bikes
hi dr james, could u give some tips how to maintain and clean your brompton bike that is 12 years old now and still look amazingly new. thank you :)
have you checked out the add-e kit?
I like how Add-e doesn't require you to saw off the air pump holder. Unlike the other friction drive kit. Main advantage of friction drive: it's compact. disadvantages: lose friction in wet weather, wearing out tires 2x as fast. www.add-e.at/_pdf/Brompton_EN.pdf
@@DrJamesT For 2 years I have the add-e on my Brompton: No, you don't loose friction, not even in very wet, freezing and muddy weather conditions.
Wearing out the rear tire is true: after maybe 2000 km I now have to switch the rear and front tire (Schwalbe Marathon) and will probably require a new set within the next 2000 km.
Other advantages: Complete system is very light - 2.1 kg including the 200Wh battery.
It's very understatement: Battery is a aluminium bottle in a bottleholder, the tiny motor within the rear triangle almost invisible.
Mounting the system is easy. An experienced mechanic should be finished in 15 minutes tops. Dismounting may be done in under a minute.
After proper mounting of add-e there's no interference with the folding, except perhaps that the seatpost sits a bit earlier (on the motor instead of the replaced bumper)
When not in use there's no friction at all. And leaving the Battery at home leaves just 900g weight on the bike. Dismounting (as well as re-attaching) the motor takes 15 seconds leaving maybe 100g "dead" weight.
And the next Generation is coming: The Add-eNEXT will have wireless sensors so mounting will be even easier and the folding untroubled.
And even though this is by far the easiest to mount I know of, there are at least annother 4 friction drive sets that fit on the Brompton (more or less well).
The Swytch kit from the Panda E bikes team is pretty impressive but is not proving easy to fit on a lot of Bromptons now the kits have started to arrive. The nano system www.nanoelectricbikes.co.uk is tried and trusted as a reliable retro fit kit developed specifically for Bromptons. Anyone thinking of fitting an electric kit to their Brompton should take a look.
I found the manuals! You can uncap the speed limit up to 40km/h. You are of course limited by your weight and 250w motor swytchbike.com/datasheets/Swytch%20LCD%20Manual.pdf

Price?????
How does this compare to Canada's Grin Techology kit?
That's a great question. Anyone out there with Grin Tech? They have two motor options.
Summary - go get another kit and be riding cheaper and MUCH sooner.
Dutch state 10-12 weeks wait for pre-order ha ha ha ha ha ha ha, I've been waiting 40 weeks and I still have AT LEAST 4 more weeks wait. OK Covid got in the way, but that could account for... 8-10 weeks delay NOT 30!!!
I'm with the other comments - sounds great and as a pre-order price it's close to other kits, but I can not recommend it with this sort of delay.
Go get another kit and be riding in weeks.
I got 10 people very interested in the swytch and they all wanted to see mine before ordering... 6 have since ordered AND RECEIVED either other kits or full bikes and I'm still waiting having now lost the entire spring and summer seasons to ride the electric dream 😡
I was always wondering whether we can install the power pack at the back side of the handle bar instead of in the front, then it won't be in conflict with the T bag top handle any more.
Little Red Cap and Big White Rabbit thought of the same. But LCD screen will be upside down .
Oliver just confirmed via email that it could be installed behind the handle bar. This will also keep the fold at the original size because the bracket is point out of the wheel instead of into the wheel.
consider these two other options, although they cost twice as much ecycles.blogspot.com/2018/02/brompton-electric-mk5.html

does this work on bmx bikes ?
Yes in the new kit you tell them your wheel size.
There is no way I would buy a kit that claims to be for a Brompton, but requires pounding the front axle into the fork tubes.
MotorheadRedo new kit no longer needs pounding. Nano kit that’s been around for 10 years requires fork widening, which I would not go for.
@@DrJamesT Have you ridden a Brompton electric? How does a Brompton with a Swytch kit installed compare to the Brompton electric model? Thanks for the info
PUS-Y mode?
My colleague got a eBrompton from ARCC Innovation, they had to stretch the front forks to accommodate the motor, will that compromise the integrity of the front fork? Is that the same for the Switch Brompton?
M Sato nothing is compromised, the motor is an exact fit with new Brompton’s fork. Slightly tight fit with older Bromptons like mine though. But sorted with a rubber end of a hammer as shown in the video
What does older mean exactly, how old?
These are quite reasonably priced and tidy kits.
However, I think the Grin Technologies kit with 500W SAW20 motor and a 36V 12.6 Ah battery is better. It will do 15mph with no pedalling on the default controller firmware, and with the Cycle Analyst V3 should do 19.5mph; although I question doing more than 15mph on a Brompton, as the brakes are not really capable of dealing with stopping effectively at such speeds.
The Grin kit, including brushless DC motor wheel, torque washers, controller and throttle, costs around 400GBP. Batteries like mine can be had from Ebay for 200GBP. My kit has no PAS, eBrake kit and no diagnostics display; these were superfluous to my needs.
The SAW20 motor wheel drops straight into the fork dropout lugs, requiring no force fitting or bending of the fork, unlike lot of other Brompton electric kits.
I had to CAD/3D print and fab a connector for my battery to enable me to wire it up, so the featured kit has an advantage, in that my conversion is a bit of a hack and required extra work, but the featured kit is only 250W, which does not cut it for my requirements.
Dewex Dewex regular Brompton riders can easily clock more that 15mph. I do question if the thin front fork can handle the high torque of a 500w motor. The torque washers it comes with must be a beast. I wonder if I can buy the torque washers separately.
@@DrJamesT The washers are similar to those on the un-modded bike in their form, but they look like CNC laster cut+bent 2mm stainless steel parts. Contact Grin in Canada and ask them if they can supply. If not, the CAD for them is quite simple and there are plenty of small companies with CNC laser cutters and press brakes who you could get to make some.
As for the torque issues, I cannot comment yet. I have been running my kit on the bike for 2 months only. It's also running on 36V and not 48V, so the torque is lower.
I have done some steep hills and rough field riding and there don't seem to be any frame geometry changes which would lead to failure yet.
I think the kits requiring fork spreading are more likely to induce failure in the fork brazing than the torque from the motor on the dropouts.
The fit on the Grin kit motor is quite good. I'd say the clearance on the axle flats in the dropout is between 0.5 and 1mm.
DrJames if the fork boss can handle the emergency stopping forces and moments of a 16 stone rider, I think it can handle being accelerated forwards from a standing start by a 500w motor. The only torque failure I have seen on a Brompton was a chain ring stripping from the crank arm on a friend’s bike once. He was probably 14 st.
On closer inspection, the washers are 3mm stainless.
It is my understanding that Grin Engineering enjoys a challenge. And, I'd be surprised if they didn't have a laser cutter. They're friendly. Call, text or email.
How much is it
$300-$500 USD
@@DrJamesT Holy mackerel !!

Hello Big League, can you share the reason why you return the kit?
I tested a production test unit. I couldn't buy it from him if I wanted to. It's not officially released yet. I did pre-order it and it's coming in Oct 2018. The final production unit might be different as he collects feedback from the likes of me. I'm testing the Zehus motor this month at £1499 it's way over my budget but worth testing for all you rich folks.
It seems that with the bag Brompton C bag or T bag, you can not turn left right just go straight, is that so?
I made a comment about that in the video. It requires further adjustments so you can turn
Thanks for the reply.
But in the video you do not see the additional adjustments, it has an image where you can clearly see the mounted extender and if it does not alter the folding, as it looks dangerous if the Swytch bag is hooked with the B Bag you will have an accident.
Those who bought the 1st 100 people paid £300 (they received the older motor, the one tested) 2nd 100 people paid £350 (est delivery Nov, i'm in this batch, bought in Aug), 3rd 100 £400, 4th 100 (£450 current price). To buy www.swytchbike.com/
How can i get this Conversion kit (inkl. Fold piece) and how much is it?
From this website they ship internationally www.swytchbike.com/ There is a 18 week wait time
This I believe is a better system, but if anyone has a comment on that it'd be good to hear! Also the new motors don't need the forks opened up. Cost is 950 euros so about 860 quid.

Don’t touch them there crooks. The half price is the full price, as no one pays full price.
Yet another idiot that doesn't understand the difference between there, their and they're!

very greedy company . the price of the same kit went from £529 to £899 in less than a year.
logic 2000 that’s the unfortunate nature of capitalism. There are whole ebikes that cost that much. This kit is all about electrifying a bike you already have and love.
Just ordered one on pre order 10-12 weeks delivery for £499
