Thanks for the suggestion. I brought it to Matt at EMPowered Cycles to repair. Apparently the root cause was a software bug in the controller. After reflashing the controller, everything worked. Matt did a great job. I would recommend him to anyone.

I have a BBS02 with a C961 controller. When I press the power button, the display no longer turns on. It worked about 4 days ago on my commute home. I've checked the battery and all connectors. Is my controller busted? What should I do to diagnose the problem? I have access to a multimeter.

Could you share a link to the mudguards you bought?

I ordered the same bike from Conhismotor. I agree with you that the Derailleur is awful. I would recommend that you replace the installed rack. Mine fall apart fairly quickly. In my opinion, their customer service is fairly decent for a Chinese supplier.

Most chargers use the same fans as desktop computers. Take the fan out, measure the size, and order another one. Your local computer shop may have the same fan in stock.

I have a similar battery on my bike. I don't have any complaints.

How heavy is the battery? Are you worried about the rack?

Bikes aren't built to go 100km/h. If you do manage to get a bike up to 100km/h, the bikes components will quickly suffer severe mechanical failures resulting a severe crash. You would be lucky if you survived. An 48v 11 ah battery has about 550w/h of energy. It would power a 6000w motor for...

If the electrical generator is always running, it won't increase range. Any energy generated will be offset by the additional rolling resistance. Since the generator isn't perfectly efficient, the net effect would be to decrease range. If the generator is used selectively during braking, it...

Does anyone have any experience using a mid drive with an internally geared hub? Does the extra torque lead to premature failure of the hub? I'm getting tired of derailleur maintenance and am looking to switch.

I have the thumb throttle. I've ordered a twist throttle to replace it.

I got a replacement set of crank arms. I'm having trouble installing them. Does anyone know of a bike shop in the SF Bay area that is willing to work on electric bikes?

Be careful with wheel locks. If you forget to disengage it, you can cause serious damage to your bike.
