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...

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...

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...

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...

I run a BBS02 and couldn't be happier with it. However, he decided he was set on using a torque sensor and belt drive. So, it had to be a hub motor. It still hasn't even gotten up and running as it appears the included controller is a lemon.

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.

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...

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 a three speed switch and cruise, so we will have to make some little pin adapters for testing. The system from Grin I recently installed went together easily and worked...

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 been frustrating for all involved. Handcycles aren't very well designed, so there are always at least TWO cans...

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. He was in the smallest cog and hit the throttle while stopped (pretty much the worst thing you could do...

I just installed a 310 on a handcycle (Force 3). Trust me. It is plenty of power. It's amazingly quiet (can't even hear it). I am also a handcyclist. I am thinking about getting a G310 for one of my bikes, as well. The one I just did is for a customer. I would avoid direct drive hubs as...

That's why you cut the top of the fork tubes and adjust the triple clamps so it has the same axle-to-crown length as the original fork. I assumed this would've been understood, but it's very good that Balmorhea pointed it out. The frame on my chopper was designed for a long fork, so it works...

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...

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...

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...
