In the USA, there are no laws that require us to use throttles in the dark of night to avoid arrest, but I agree that part of the fun in biking is the pedaling. I'll understand the needs of those who are physically unable to pedal, or those who are using the bike for transport.

I've ridden 80 out of the 127 days so far in 2024. In January-Feb I got out 24 times. Only ride when it's above 40F, with sun, and no ice on the pavement. . We're 30 miles west of Chicago, and we had a mild winter. Didn't use my snownlower at all this year. Nice thing is my wife will join me...

Have you downloaded the user manual? https://manuals.plus/m/9c3a7f52a4ac4264534cbe54e8ecf4f655b6ce36f8523953da3ec946f1cdf49e_optim.pdf These basic ebikes are very similar anf will have the following schematic. The controllers all have similar connection categories> 1. Motor is three phase...

Did it ever work, or did you buy it nonworking? =Make sure neither of the brake levers are allowing the brake switches to engage. That will inhibit the motor. -Has throttle ?. Three pins. Power-ground is 45V. Signal shoiild vary from 0V to 4V when throttle is turned. -Has pedal sensor? Three...

Must be a Trek owners manual that covers this. I wouldn't want to contradict what they say. I do long term storage at 30-40%. That's the same level required for shipping because it's safer. By the way, your Trek will shut down around 30% to protect the battery. You can't run it to zero, If...

This was two years ago. When I started DIY conversions nine years ago, the dangers of front motors snapping off cast alloy suspension fork dropouts was well known. He is so lucky that they broke off from a standing start. I think most trikes use steel forks, but even steel can bend and lose a...

On my controllers, I get a throttle error if the thumb lever isn't returned to zero when the bike powers up. It's a safety check done by the controller to make sure the bike doesn't take off when turned on. I use sponge rubber handgrips and they often slip and hang up the thumb lever. Took me a...

This is my next conversion for my wife, a Biria. They advertise it at 32 pounds. We're looking for easy dismount. I have the bike delivered in the box, but I haven't opened it yet. They selll an e-version with front hubmotor and battery in the rear rack for $1999. I've already got motors and...

Honda does make great generators. Here's their e-scooter. Around $1000. I had a test ride, Not for fat old geezers like me. ,

I've always thought I would get better range using cruise control. I don't have cruise invoked on my KT controller, so can't test it. However, if I just watch the wattmeter, if I use throttle to maintain speed, the wattage shown is lower than when I pedal. However, that level is quite variable...

If you were to switch to 26x3" tires with street tread, you would find they roll quieter and faster, Your speedometer would have some error though, unless it takes the actual tire diameter.

KT controllers are current based, and I think they feel better on pedal assist than other brands of controllers I owned. This is my belief on how it works. Easier to visualize it with a front drive bike, Total speed depends on power to both wheels, right? With a current based system, the...

After watching vids of e-mountain bikes at the 2024 Seat Otter expo, I'm impressed at the technology and design for the suspensions. I now see the reasons for electric shifters. Recessed buttons on a road bike with no exposed wires/cables do have lowered air resistance. I could see how...

If it recharged, congratulations! I would imagine that Alva's battery management circuitry is much more sophisticated than a lot of the cheap stuff in many of today's batteries. If it didn't go to sleep forever, it's probably in good shape. I would suggest riding a few times to see if it has...

A BMS should be able to shut off on a short circuit for protection, and then reset itself when the short is removed, especially one with all that circuitry. Have you tried plugging in a charger to see if it wakes up? I have no idea what Specialized does, but some proprietary batteries will...

Your KT controller label says 18A peak, so that's around 900W peak at 50 volts. That part is real. If the battery is big enough, their controllers will deliver up to peak power,. Hard for a fat tire trick to put that power to the ground though, and probably hard to make a turn at full speed...

Go to a bike shop and arrange for a test ride of a torque assist system. See if it does what you want, It's possible to get exercise on most any any bike. Just set the assist low and go faster than what it will support. Some cadence systems are fairly responsive within a given speed range, but...

If you didn't get 4.5V on the throttle, the controller is probably toast, The same 5 volts powers the data lines to/from the LCD3, any pedal sensors, and also the motor sensors. It could be amy of the latter units loading down the supply While waiting for a new controller, I suggest you find...

Seems like the controller is fried. I'd hold on the display til you try the new xontroller.,
