im planning on running this exact setup on an older dh bike and nice to see the speed this thing can hit. big upgrade from my current bike in every way

what size os your chainring and do you have any issues with chain rubbing the chain stay on smallest rear cog?

I connected everything and the motors spins kinda slow when testing any advice

lol geese

I know it's a bit of an old video but I've just done this tour and was just wondering what type of bikes these were, Thanks :)

is this the same build that you had the controller outside.

Just over volted my revv1 with a 72v35a fardriver and a 72v battery. Results look similar to what you’re experiencing, maybe a little more torque but the motor seems to have a speed limiter. I’m pushing 35a line and 160a phase. Not exactly sure what else to do to get more speed. This winter I’ll hook up my 72v 5000w motor.

Are you plugging the power for the stock revv1 display to the second battery??

is there a way to get in touch with you by email to ask a specific build question? You did a sickkkkkkk job! Tried finding if you had an instagram to message but couldnt find it. Thanks

Can you put helmet headphones in it ?

link to rear shock please

You can get more than 45A from the phaserunner. You need the external heat sink for it ($10) and it will throttle back to 65-70A. Phaserunner is made by ASI and way more dependable than Chang Chung controller. 7:15

Thanks for the great video! Did you ever end up making more extensive upgrades to the BRAT? Sounds like a Super73 battery is a good place to start for added range?

great video, what is the spec on the motor and battery on a stock Rumble?

What would be a good ebike (brat style) for tall riders, I'm 6'3"? Thanks.

Change your chainring to a Lekkie.

I got a 500 Bafanger on the way. The OG controller is going to stay in the box. Do you think you could handle 1500 watts of sine wave? I'm not looking for top speed I want that acceleration! The shunt mod is out of the question. I don't trust it.

I have a ghostcat f3 1500 watt, I want more speed and want to do something similar.

You running stock motor on drt?

I'm currently building my 4th ebike & this time I'm doing a full suspension bike using a very rare frame I've managed to get. It's a BeOne Hornet Plus frame with Manitou front & rear suspension, 26" Mavic front wheel & a rear 26" 250w stealth hub motor, with a 35ah controller, also a Bafang BBSHD mid-drive, 52v 28.8ah battery & dual splitter for power supply enabling me to use which motor i want at the time 😊

Bought the same yesterday. What a blast!

For the record, higher voltage does add a little bit more heat but most of your heat comes from your amperage. Generally speaking you're better off increasing your voltage than increasing your amperage. High voltage is the future.

I’ve always liked this Super73 frame to bad it doesn’t have real suspension, the frame like all Super73’s are very customizable! Nice clean build by the way

Where do you get the battery cover for those super 73s at

Hey man I have a upp 72 volt 40 amp hour 288 watt hour battery like you said it costs around $700 some dollars and I'm trying to find a frame that will fit into so will it fit into the super 73 RX frame

I want to install that controller on a 52v 20ah 40amp with a 1500w motor. Do I need a power source other than my display and existing throttle? I see your throttle have a key and seems to be connected to a power source. My bike throttle connects to the controller with no other power source.

Would love to meet up day at the dam and get some FPV drone shots.

Hey man. Not sure if you know this but if you jump the 3 speed connector on that controller you can get speed 3 or speed 1 depending what you short out. Default is speed 2.

Letsss gooooo

Can I do this with my S2? Any tips?

Dude thats sick! Exactly what I'd like to do with my bike. I'm not a mechanical/technical guy so any help with upgrading mine would be greatly appreciated

Hey brotha from the same area. Would love to meet up and pick your brain on your build. I have the same bike and want to do exactly what you have.

Revv1 is a beauty

Dont buy it. after purchase good luck getting anyone to do something for you.

How fast does it go now?

The mirrors are perfect.

great bike

What lcd displays will work with dis controller

I bought one about a year ago, but just used it for the first time this morning. It's awesome. I already bought another one for an upcoming build.

If you use the throttle with the speedometer..what wire do you connect from the controller to the throttle to get the speed??

Yeah one direct drive rear motor doesn't have the torque for stuff like this. I know this is a year later but the grin fat bike rear hub can probably do it now. But either 2 direct drive motors or a geared hub in the rear.

Do you know what the controller is called. The link doesn’t seem to be working for me down below Thanks for the vid Love the bike I was about to buy a phaserunner like you others saying they can’t get where they want with it

I’ve seen a few folks wheely the stealth bomber. I got a 72v 35 amp stealth bomber.

Hey would you be interested in doing my custom Revv1? I already have the controller. I'm not too far from you.

Is now a good time to ride this trail because it looks like this was recorded in winter or something? I just need to make sure there is water during this season.

You're the first reviewer, I've EVER heard say this bike had a hard time on hills. I've actually heard them all say it was one of the best on the hills in particular. I'm shocked. I've even gone back as far as a year. You may have a lemon..😮

I'd be mostly worried about the tires if anything because they're not ready to go that fast unless you got different than what it came with

How many amps is the controller?

I really want this one I just can't justify the price for the power and range output despite it looking really cool. If it was 1800 absolutely, but for the price. I think the battery should be at least thirty amp hour, and 1500 watts, and 40 amp controller 😂 You can get two bluetran lightning 72volt 32ahLG battery and 5000watts 50 mph.scooters for the price of this.
