Trek Marlin 1500 vid, hey thanks for those close ups. Simply liked nerdn' out to your posts. Despite my height of 5'9" you almost have me, atleast thinking about trying out a 29r. It's all about that ride!!! thanks again JohnnyNerdOut!!!!
I used a used perfect large Surly Krampus and fork with the BBHD and it turned out great. I was looking for a medium but couldn't pass the deal up. I'm 5'10" and so I can ride either a large or medium. I am looking for something like it in a medium and a small frame to build for my wife. I like your idea of buying good quality used bikes but I would like stay at or above the Surly quality. If could spend 500-1000 bucks per frame for used hardtail 29er steel bikes similar to the Surly Krampus, what would you look at? Seems my biggest challenge was finding the correct chain line and front gear and spacers to clear the chain stay. Seems like older aluminum and carbon frames wouldn't be a good idea. What about something like a Canfield hard tail ? I'm thinking of maybe stepping up into a better frame that is a little shorter but about the same length. Any Ideas?
Heh never enough bikes,... yeah I realized the first time I tried pedaling on beach sand with my 2" wide tires got me thinking why I will need a fat tire bike if I plan on going out to Arizona to ride in the desert
Hi! Which hardtail can fit Lekkie 52t on a BBSHD not hitting the chainstay? How will it it impact on chainline? I'm willing to sacrifice some lowest gears though. This will only be a commuter. Hope you can answer.
Hello. Very interesting content! In your opinion is it possible to fit a 30T or 34T Chainring on a Trek Marlin 5 with the BBS02 with some accessories or standalone so to get a good chain alignment?
Awesome build! I am thinking of doing the same set up with a Jamis Divide but I am unsure about the Bottom bracket. Info on the website says it is a sealed bb but no info on the size of it, I know it needs to be 68mm for the BBS02.
Hey Johnny! This is exactly the bike I have and am preparing to convert. Did the motor fit without the need for spacers on either the bottom bracket diameter or to clear the chain stay? Say ok if you don't remember, or don't reply, I'm just excited to see you already did this one. Thanks! Tim.
@@JohnnyNerdOut lol more than likely, yep, but you are free to be yourself and do your videos how you want too. It would have been handy to know the answer to my question but ultimately I take responsibility for my own info and build 👌
at 1:25 i think he says its a large, yeah I'm having the same problem, i ride a medium size bike but i think most of these videos show large bikes. I went to bafangusa direct and printed out the cut outs for the batteries so i can take them to the bike store and see what battery will fit. I'm hoping these batteries fit in a medium but if not i might just buy a large bike, i'm 5"9 so i should be ok. Some Trek bikes are a M/L.
Hey Jonny, can you confirm for the marlin 7 a few q’s for me? Did you use the stock 46t began chainring and if so did you have any issues with alignment? Also I assume you used a hydraulic brake sensor. Could you do a more in-depth video on how to install them properly please? Absolutely love watching your videos and it has given me the confidence to start a project of my own. Thank you
Hi Johnny, quick question - I'm thinking of purchasing the Bafang BBS02 mid drive kit from your website for my 2022 Trek Marlin 7 but my concern is that according to Trek's website for the Marlin 7, the max chainring size for a 1x is 34T. I saw that you sell a Lekkie 36T, would the Lekkie 36T work on my bike or would I run into problems? Thanks.
Hi ....so how durable is the frame? I'm trying to put it on a marlin 5 aluminum frame... Theyre saying the frame will crak quiet easily with a bafang motor how true is that?? Thanks
Great video I just bought a built 29” Satyer 200 aluminum frame from a guy who installed a mid drive pedal assist I want to upgrade to a Bafang. Love the bike but really need a throttle how much difference is there between a 48 volt and 52 can the 48 be upgraded to the 52 volt battery later down the road Thanks
Glad I found your channel. I've been wanting to buy an ebike really really bad. But since I already have a TREK FX1, I'm thinking maybe I can easily convert it with a BBSHD.. just wish I knew what I was doing. 😒
Great video! Do you think that this bike would benefit from a 42t up front to improve the hill climbing? I've got a Marlin 6 and top speed on the flat of 20-25mph would be fine for me, but my area is very hilly and I might want to try some mild single track on it, thanks!
@@JohnnyNerdOut thanks mate! One last question, do you think that you can get much exercise using the BBSHD or does the motor spin too fast so you're not getting much cardio, without "lugging" the motor and running it at low RPM/cadence?
Hi Johnny. I have a Ktm scarp mountain bike that I want to convert to a ebike with a bafang BBSHD motor. The problem I have is that my bike as a bb with a pf41. Meaning that the push fit bearings is a 41mm. My question is that leaves about 6mm for the bb wall and I have a cable coming around the underneath. Is the only option to reroute the cable with the wires from the motor etc ? I don't see being able to squeeze it between the bb shell and the motor? Please advise, many thanks Robin.
I have the same type of bike with 52 teeth on the motor and 40 to 11 tooth rearsprockets . My 750 is fine but my 48 volt is a little weak. Should I buy a 72 volt Samsung?
Hello Johnny Nerd Out! I have been looking into converting my 2019 Trek Dual Sport 3 to an e-bike. I am having trouble finding the size of the bottom bracket. I want to go with a Bafang but I don't know what size bottom bracket I have. Any suggestions?
For hills, definitely a mid drive would be superior in performance. It does require more emphasis on biking fundamentals though, so they might not be the best for new bikers.
I just got the BBSO2 motor with a 52v 21amp battery on my Trek 4300. Is that battery overkill? should I change to the 52v 17.5? Or are they similar in size and weight?
Honestly there’s no such thing as overkill when it comes to battery capacity. I think you did good. Unless you can’t afford it then you might want to think about exchanging it for the smaller one
DUDE! I just stumbled across your channel and I'm sooooo happy I did. I just got a very similar bike from GT, the aggresor 29er expert. I was positive I was going to do a ebike convertion to a 1500W rear hub setup. Now that I've seen your video about mid drive vs. hub, I'm positive I'm going to go with a mid drive. Only big question I have is should I find a mid drive around 1500W vs. the 750 in this video? I want more power than range but sounds like this is pretty sweet on 52v and with the benifits of mid drive. Should I bother with more motor power?
The BBS02 rated at 750w puts out about 1500w at peak. It’s pretty powerful. The HD puts out a little over 1700w at peak. If you want more you need to go either cyclone or cyc motor. Personally I think 1700 W is a good amount and anything more than that you’re starting to put more and more strain on your bicycle components.
@@drumbum962 If you get the BBSHD you can get a better controller and use a 72 volt battery and run it at over 3000 watts without problems. I never understood why Mr. nerd has never explored this option.
Is there a way to set this motor up in a way that it's pedal assist only, no throttle (maybe even no screen) just a clean electric bike, I'm also considering the bafang stronger version (1000w forgot it's name). Do you think this is agressive enough and will this actually give me any significant range difference. And one more question for you e-bike nerds - is there something similar to the bafang motors but with a torque measuring system
you dont have to connect the throttle, just leve it off. you do need a display though, but the 500c is a nice small one. Check out the tongshen motor if you need torque sensing
The sw102 display is the sleekest i could find for those....but be careful some versions are programmable to unlock speed limit and so on while others are locked by firmware
Hello. Quick question. I'm planning on a bafang 750 middrive system and the only uncertainty is the brake terminology. When u say hydrolic braking does that also refer to mechanical disk brakes, or no. I have a norco with mechanical disk brakes. Which brake setup system do I select in the options? If someone can get back with this, that'd be great. Thank you
Hey pal, thanks for all of your informative and entertaining content. I've been really enjoying your channel and I was on the path to get an e bike so it has been quite fortuitous! I make an appointment to talk to you on your website as I have a lot of questions but I was just wondering if you have converted a Trek Roscoe 7/8? I'm living in Copenhagen and mid fat or fat tyres bikes are thin on the ground - I want something to go on camping trips in the woods and to get around town a bit easier and more cushioned as I have arthritis in my spine. Thanks again. Keep it coming. X
Is there a 500w mid drive motor that has the same housing as a 750w or 1000w motor. I have to be under 750w in my state and I'm thinking I could buy a 500w bike and up grade the internals of the motor and controller and still have a 500w stamped motor.
@@JohnnyNerdOut have you looked at the 500w truck run motor on the rambo cruiser? Is it the same as a 750w or 1000w or should I be looking at something else?
Hello i have a marlin 7 2021 this motor bbs02 fit on my bike the information is botton braket FSA, 73mm, threaded cartridge, 122.5mm shaft. Thanks sorry for my english! Thank you a lot!
Do you think a crown of 32 is good in this bike the transmission of the new marlin is 1x10 with a crown of 28. I worried about the chainline with the bafang.Thanks!
@@darlemherrera6158 try the stock ring out first and make adjustments as needed is what I usually recommend. You could probably add teeth since your adding power.
Hey Johnny. I have a few questions about buying a used bike to convert to an ebike. What’s the best way to send the info to you instead of putting everything under the comments section?
Thanks for the video. I really appreciate it. But watching the video has raised a couple of questions for me: 1. Is the Trek Marlin 7 about as good an all around bike as you can get, especially for the price, to convert to an E-bike, or do you have any other suggestions? 2. I've seen TH-cam videos stating that the Bafang controller is not that great, and it's recommended to replace it with an external controller. You've never mentioned any problems with the Bafang controller and I wonder how you feel about it.
1- pretty much yes....As long as its what you personally need. but yes IMO. 2-I have had one issue with a BBS02 controller in about 350, would not even waste a single calorie thinking about it
@@JohnnyNerdOut Thanks for the quick response. I think the people who were advocating an after market external controller were looking to max out the engine more than the stock controller allowed. Last question: I noticed in the speed test you weren't pedaling. Do you think you could have gotten a higher top end if you had been pedaling in a high gear? When it comes to E-bikes I don't mind throttle assist but I mainly want the bike to feel as much like a bike as possible. I've had motorcycles (and 300cc fuel injected scooters that could cruise all day at 80+mph and still get over 50mpg), and I'm not looking to replicate that on an E-bike (like the Sur-Ron, for example).
@@JohnnyNerdOut That makes sense. Plus, I saw in another video of yours that you stated that when you do the speed test you only use the throttle to demonstrate the "pure" speed of the throttle assist with no pedaling. That makes sense as well. Great job. You've definitely opened my mind to a more economical higher quality E-bike option.
Could you make that bike with a ultra max motor and then program it so its less than 750w so im league to use in nh? I would also need a 700w sticker over the 1000w stamp on the motor and a class 2 700w 20mph sticker on the frame. And a receipt saying its only capable of 700w would keep me out of trouble with the game warden.
@@JohnnyNerdOut I have the engineer's at bakcou ebikes working on programming a mule below 750w for 4300$. Thought I'd ask if you could make one for less money.
@@fulllfreezer yes I can. It would use the BBSHD motor instead of the ultra. I actually just finished a bike that is pretty close to a Mule clone today. I believe the total cost including bike was around 2800$. Bike was a Motobecane 26x4.9” with hydraulic brakes
Here in NH I have to be under 750w to be woods league. 750w and up would need registration and written permission from land owners everywhere i go. Does anyone make a mid drive less than 750w but more than 500w
Yours look so clean and cluttered. I watched another vid and the guy has wires all over the place and I wouldn't want to ruin the look of my beautiful Marlin 7 with that S%#t! I Gotta ask, what year is yours? My 2020 has an angled and flat top bar. Great vid though, I ordered the gear sensor which I wouldn't have done otherwise and it is good to see how it will look!

I've had motorcycles (and 300cc fuel injected scooters that could cruise all day at 80+mph and still get over 50mpg), and I'm not looking to replicate that on an E-bike (like the Sur-Ron, for example).
@@skaybaltimore yes I could’ve gone faster. I rarely use the throttle on my bike. I always use the pedal assist 👍
@@JohnnyNerdOut That makes sense. Plus, I saw in another video of yours that you stated that when you do the speed test you only use the throttle to demonstrate the "pure" speed of the throttle assist with no pedaling. That makes sense as well. Great job. You've definitely opened my mind to a more economical higher quality E-bike option.
Could you make that bike with a ultra max motor and then program it so its less than 750w so im league to use in nh? I would also need a 700w sticker over the 1000w stamp on the motor and a class 2 700w 20mph sticker on the frame. And a receipt saying its only capable of 700w would keep me out of trouble with the game warden.
ultra motor needs a specially designed frame to house it
@@JohnnyNerdOut I have the engineer's at bakcou ebikes working on programming a mule below 750w for 4300$. Thought I'd ask if you could make one for less money.
@@JohnnyNerdOut i like the heavy duty gear drive motor and maybe in the future the nh law will change and I can get it program for more power.
@@fulllfreezer yes I can. It would use the BBSHD motor instead of the ultra. I actually just finished a bike that is pretty close to a Mule clone today. I believe the total cost including bike was around 2800$. Bike was a Motobecane 26x4.9” with hydraulic brakes
@@JohnnyNerdOut you could cut a frame and weld the plate in for the ultra max motor ,theirs a kit for it.
Here in NH I have to be under 750w to be woods league. 750w and up would need registration and written permission from land owners everywhere i go. Does anyone make a mid drive less than 750w but more than 500w
They usually make them in increments. 250,350,500,750,1000 ..... so unfortunately no. 500w is still a decent option
@@JohnnyNerdOut is there a size difference between a 500w and 750w motor or are they the same and the controller and battery makes them different?
@@fulllfreezer same size. Just firmware Tops it out at 18amps vs 25
@@JohnnyNerdOut can you chang the firmware to something closer 750w
@@JohnnyNerdOut game warden will only look at motor size stamp and class 2 sticker. It would be league to make a 500w closer to a 750w
Yours look so clean and cluttered. I watched another vid and the guy has wires all over the place and I wouldn't want to ruin the look of my beautiful Marlin 7 with that S%#t! I Gotta ask, what year is yours? My 2020 has an angled and flat top bar. Great vid though, I ordered the gear sensor which I wouldn't have done otherwise and it is good to see how it will look!
That’s what I built a 29”
Did you use the stock bafang front sprocket? I have a 30T front and it has alignment issues with not enough offset.
