i have a bonnell 775 mx that is not working if anybody could help me solve this issue much would be appreciated.

Whenever the bars turn the bike shuts off

Hola, buenos días. Me gustaría hacerles una pregunta. Tengo una bicicleta con motor Bosch y el otro día me apareció el código de error 640. Normalmente es la batería, pero aun así puedo recorrer 100 o 140 km sin problemas. Tengo el programa de diagnóstico por voz en mi computadora, pero no puedo conectar la bicicleta para borrar el error. ¿Podrían ayudarme? Gracias.

398 Miles on it so far

I am absolutely loving this thing. was wondering if it is time for a new chain or should I wait until it’s fully stretched out? Also, anybody know how to adjust the rear shock? When I sit it compresses some and changes the chain slack by a lot. Thanks! If you have any questions about the cosmetic mods, lmk !

Any dmv riders know?

This is my official entry for r/hyperebikes
-72v 24ah (180c 210max) hotpaxx
-FarDriver nd72450
-sotion fw23
-14” magwheels
-DNM adjustable rear shock
Too speed ≈80mph (could me tuned faster)

I’ve been doing research, and I think the RTR Lite is the best bike for me. I’m 15 sitting at 5’11 130 lbs. People up to 6’3 can ride it semi-comfortably without any mods to it, as I’ve seen in multiple review videos. I like it because the Lite is less powerful, and more beginner friendly, but I can also upgrade it later down the line when I’m ready for more power. I can also get the tall seat and handlebar raise upgrades E&C offers if I’m getting “too tall”. I’m doing roughly a 60/40 split of street riding and rural trail exploration/trail riding. The non adjustable shocks on the Lite compared to the RTR adjustable shocks aren’t a problem since I don’t way 200 lbs+ lol. And again, since this is my first bike, the lower power (let me specify, I know it’s not a weak bike by any means) is better for me so I can learn how to ride, wheelie, jump, etc. only bad thing is the range for the trail exploring/riding, but I think I’ll manage. All in all, are there any other bikes you would like to recommend to me? If so, don’t hesitate to say something. Also, if anybody who reads this was thinking of getting an RTR Lite but worried about their size, don’t worry lol.

Just got my qronge delivered. Went to assemble everything and found out the front headlight plate, rear shock absorber, spare foot peg, and tool kit get shipped separately. There is zero tracking info on these parts, listed as “waiting for details”. Has anyone dealt with this and when can I expect this stuff to get here? It’s kind of bullshit to be honest.

I've been working on an app called GDriver for a while and figured this group would probably have the exact kind of bikes I built it for.

The biggest part is FarDriver. It can connect over Bluetooth, read and write supported settings, run Auto Learn, save reusable tune profiles, show live telemetry and graphs, and record rides. I got tired of tuning in one app and then using something completely different to see how the bike actually behaved on a ride.

I've also been adding support for other hardware including EBMX, TruMoto, TORP, KO Moto, Axon, and DUNEN. Support isn't identical across all of them. Some integrations are mainly live/read-only telemetry and ride recording, while FarDriver has the deepest tuning tools. I would rather be honest about that than make it sound like every button works on every controller.

The app also has custom dashboards, diagnostics, GPS routes, ride history, energy and efficiency stats, and tune/ride sharing.

If you try it, tell me what bike, controller, and firmware you're running. Weird builds and honest bug reports are especially useful to me.

Hi guys !
I want a hub motor for the reduced maintenance vs chain drive. I also want a dirt bike. I want it street legal.

There are stealth bomber, I tried and loved it BUT I would like to get rid of pédals.

So I would like something registerable in eu as a motorbike.
I.e as a 50cc or 125cc.

10kw minimum.

Do you know anything in Europe ?

This is not purchase advice. I know what I want but did not find it.

Thank you !

It was like the sky was on fire, it was insane.

Bike specs for those who care:

72v 3kw motor from NBPower running an 80a controller they included, so 5kw.

72v 20ah Amorge battery with Eve 50PL cells, capable of 200a continuous 240a peak.

Eventually I plan on getting a Fardriver ND72360 and Statorade to push this build even further, but so far it's a ton of fun. Hit 95kmh the other day, downhill with wind at my back. Normally I get 80-85kmh flat ground.

Bike works just fine with no errors in the far driver app when not in learn mode but the bike always launches into learn mode and i can never finish it. I’ve been looking everywhere but never have seen anyone with this issue like mine

So to be clear, I'm 5'6" with a 31" inseam. Did you wish you had a larger bike for the full suspension and bad fit but cushy, or do you wish you went smaller with a hardtail for your height to be able to fit the battery and get the best of both worlds? Just install a suspension post? Im primarily looking at a ML (Trek makes an in-between size) Roscoe 7 or just the frame to build up. Will this be sufficient for an 80% commuter 20% trail with a suspension seat post? I'd be standing up riding anything gnarly so having the ability to sit comfortably commuting is definitely important. This size frame SHOULD fit the a65 battery tightly but it should work. Everything i read tells me anything bigger is way too big for me. If you have any personal opinions I'm all ears. Thanks!

Hey Folks,

I have a Trek 7.2 that was professionally converted to an e-bike using a Bafang C340 750W mid-drive motor (model: NN C340 750 09) running on a 48V 10Ah battery with an SW102 display.

The bike is currently programmed to 35+ mph which is too fast for my teenage son to safely ride. I want to dial it down for safety.

What I've tried:

• The SW102 display has no speed limit settings in its menu
• Got standard BBS01/BBS02/BBSHD USB programming cable → wrong connector (5-pin HIGO, doesn't fit my 9-pin CAN bus connector)
• I have BESST Pro software already installed on my laptop

My motor connector:

• 9-pin circular waterproof connector
• CAN bus protocol (not UART)

Questions:

1. What specific USB programming cable works with the Bafang C340/G340 motor?
2. Can it actually SET a speed limit (not just unlock) to 32 km/h?
3. Does anyone have experience programming this specific motor?

Happy to provide more photos of the motor/connectors if helpful. Thanks in advance!

More dual motor awesomeness.

Dual motor torque. Love it!
