I had a KT controller that would shut down above 55 volts. It was on a dual motor cargo bike so the other motor and identical controller would get me along until the voltage dropped below 55v then everything worked fine.

I’ve done a fair amount of unsupported ebike camping trips. I learned early on to plan well below the range of my battery pack. The longest day I ever had was 100 miles and that was because there was absolutely no place to stop for the night. I tried to stop at state parks where I could usually...

I doubt that any of the settings you changed caused the problem. Poor electrical contact for whatever reason leads to increased resistance and heat buildup at the connector. If you replaced it with a new one and have a solid connection your problem is solved until the new one wears out. Each...

My current bike packing rig is a Surly Big Dummy with aBBS02 mid drive and a Q128 slow wind geared hub up front. It’s a heavy awkward beast but the nicest ride ever. This is my third iteration of dual motors on this bike and the best so far. I run the mid drive all the time in pedal assist mode...

video is about removing controller on a LECTRIC ebike of the same folding configuration. I’m pretty sure your controller will be in the same place.

Below the seat post tucked in behind the battery connector.

I’ve always wondered if wireless pressure transducers like those used in automotive tire valves could be attached to bike pedals in a way to gauge how much force the rider is putting into pedaling. It would be a way to achieve torque sensing pedal assist.

Fix the speedometer and report back

Good to have you back Dan. You may have gone to the dark side but we know you still have a wealth of knowledge for us electron lovers. Pop in and share your wisdom whenever you can.

Funny, I never thought about having to purchase packaged sand but I’m a desert dweller and it isn’t hard to find here in Arizona. It doesn’t need to be pure, any loose dry dirt will smother a fire. Yes those are the bamboo sticks I use. very handy to have when soldering or spot welding small...

Interesting project Jared, hope to hear how it works. My thought is that adding a small battery to the circuit to buffer the fluctuations in solar output would help protect the motor from heating up in near stall conditions and provide a bit smoother and more predictable performance.

I put together my first ebike back in 2010. It was a Walmart granite peak mountain bike with a front hub motor and 30 pounds of lead on the rear rack. It was an ungainly piece of crap but I immediately fell in love with the feeling of cruising silently and getting some exercise without giving...

It would be interesting to know how you regulate the three motors. Are they linked to a single throttle? I have dual motor Big Dummy cargo bike with a BBS02 mid drive and a geared front hub. I couldn’t get the two motors to play well together using a shared throttle so I set it up to use pedal...

Fechter, as another victim of too many calendars past, I’m hoping you will elaborate on the success of the mobility device excuse. Would it help to carry a letter from a MD? There are places where the rules change on fire roads and trails as they cross jurisdictional boundaries and you can find...
