Re: How did I mess up my hub motor system?!!

The motor and gears turned smoothly when I took it apart. I checked the movement at each step of reassembly, too. The XT90 didn't melt down. I saw a bit of smoke and yanked the connector. It may not have been seated all the way. I was testing it with the wheel elevated, so there was no resistance on...

How did I mess up my hub motor system?!!

I have an old BMC V2T hub motor that I use to power a mobility trike that I put together. It's been working amazingly for the last several months. However, I recently realized that I had only put two bolts in the brake rotor :shock: So, I decided to put the rest of them in there. However, I forgot t...

Re: Which CA2 for NOS BMC/Lyen setup?

Thank you for the advice. I thought the same thing. I tried the controller with no CA, but I got no throttle response. I'll have to check all the leads with the throttle and make sure it's providing voltage. If I need to try a different controller, are there available options other than cheap/crappy...

Which CA2 for NOS BMC/Lyen setup?

I have had an NOS BMC V2T motor and Lyen controller (12-FET 4110) sitting in storage for ages. I got it from Mr. Brouk when E-bikes SF was still around. I'm FINALLY getting around to deploying the system, but I believe I need a Cycle Analyst V2 in order to run the system. For a Lyen controller with ...

Re: Will BBSHD work okay to drive dual 20" wheels

With low gear ratios, a BBSHD would have no trouble. With creative use of freewheels, you can create an inexpensive "differential" for the rear wheels.

Re: New cargobike build input before purchase: 52v Gmac 26" 8T or 10T (moved from E-vehicles)

I'd go with a 10T. If you're ever moving 400 pounds (of you and cargo,) you'll want gear advantage. Wind resistance at 35 mph will be considerable. Using a motor that will only occasionally see 35 mph but suffer all other times doesn't seem like it would meet your needs. For a battery, I'd consider ...

Re: Unresponsive MAC/Infineon/EM3EV system (new build)

connect the throttle directly to the controller, with the ca completely disconnected and out of the system. that will eliminate any possible problem with the ca or it's wiring. That is great advice. I will have to give that a try. I believe the throttle input for the controller is the kind that has...

Re: Replacing MOSFETs in a Grinfineon controller.

And assuming a capable user, a bit of "how to refrain from breaking your bike" training should go a fair way? Indeed. I don't know how he ended up stopped while in the highest gear. I think going for the throttle was more out of frustration than anything else. The build for this bike has ...

I am still working on it for him. I have to replace the MOSFETs in the controller (Grinfineon 20A). His Force 3 had a manufacturing defect that caused the chain to bind and stop the wheel.

Re: Converting a beach cruiser with front wheel motor.

On a chopper, a strong front brake can be just about as dangerous as insufficient brakes. A triple clamp fork set up low over the tire can use strong front braking. The stretched chopper forks I’ve had can’t use strong front brakes to their potential, though. The front wheel skids from anything mor...

I'd buy a cheap dual-crown chopper fork with a disc mount and use that with a front hub motor. I have a Nirve Cannibal with a Nexus 3-speed hub with coaster, and I welded a disc tab to the front. Stopping power for this type of bike is VERY important. One mishap would be far more costly than any bra...

The 310 will have plenty of power for a road bike. I recently installed one, and it's dead silent. It should be plenty sufficient for a road bike that is also utilizing pedal power. Having the wiring come out if the hub makes things a little cleaner. However, one thing to note is that the 310 isn't ...

Re: 2cycle to electric conversion

I'm also of the mindset that OP would be better off with a 1,500W (or less) motor and a big battery. Going beyond 30 MPH really starts to eat up the watts, and that gets expensive in a hurry. Especially on a bike that has both on and off-road capabilities. I assume OP's Trek MTB is a hardtail (hopef...

Replacing MOSFETs in a Grinfineon controller.

I recently delivered a handcycle to a customer after adding a Bafang/Grinfineon e-drive system. It went together well and worked BEAUTIFULLY when I test-rode it. Same for when the customer took it for a brief spin. Unfortunately, some poor manufacturing/design of the handcycle itself led to a chain ...
