Sure sounds like it’s bad, unless plugged in backwards.

Which bike do you have?

Just found this while searching for another item. The clunk is when the bike is going faster than your legs so the engagement point of the freewheel is random. The fix for this is a technique while coming out of coasting best described as the practice of ghost pedaling while slowly increasing...

A car is no challenge if you ride the brakes LOL. It’s the ultimate challenge at the edge of vehicle capability.

I’ve always been nice to them about parts but did get a supervisor involved over a motor once. Two Radcity total of 11,000 miles with zero problems on one except for broken inflator valve on delivery. Awesome company, just way too busy sometimes.

Good idea

If you’ve ever been down a steep mtn road on an ebike and your brake pads glazed over you won’t do it again. Dragon is way more fun in a car. Plus you can buy a picture hanging in a curve.

If you still have the bad controllers I would like them. I will reimburse for shipping. Message me.

I looked several months ago and none to be found with the correct dropout spacing for a city. 135mm I think it was. 140mm will fit too. Anyone know where to find one around 1000 to 2000 watts geared with 135 to 140mm dropout spacing?

Thanks for the link. Mine is still working and turns the ole city into a different bike. No issues with battery because you hit top speed so quick. Hilly country would be a different story but I advise people to walk it up real steep hills rather than cooking the whole system and risking a...

If you had a programming device connected to the unused cable under the bottom bracket it probably would have started a flash process.

UPS sounds like USPS now. I received a fragile package from USPS once that they put a sticker on that said broken when received. Like my friend sent a broken item to me, yeah right.

Many places say it’s shipped when they tape up the box and sit it by the door to be picked up. Then it might get picked up anywhere from that day or 3 days later. Then it goes somewhere and waits for it to be processed which might cause active tracking info or might be at the next stop. Even a...

The lowest wattage you can get on the Bolton upgrade which is same as Electro world is around 90 watts on PAS 1. Rad is around 50 watts. My Bolton has three choices for overall PAS level. These 3 affect all 5 PAS levels. The only other way to affect the power is by setting max wattage division...

For ebikes that have riders not interested in applying full pedal power the seat can be up to 3 inches lower than typical and still have a comfortable ride.

If Rad has made anything hard to work on or extra expensive parts to replace it will really cost them on warranty repairs. Also more unhappy customers. They need to gravitate towards easier to replace controllers with locking mechanisms.

There are ebikes with controllers in the motor so might even be in the battery. One geared motor has the battery and controller inside the motor. https://www.electricbike.com/five-hubmotors-with-the-controller-built-inside/

Some chainrings have pins as a helper for changing gears from smaller to larger chainrings on multi chainring bikes. I could grind them off if they interfere but for now I’ll see about flipping the ring over and using the other edges. Some rings advertise that as a double life technique.

It seems that something happened somewhere or their attorneys told them to eliminate the speed bump up. I think it started in 2020 on all Rad bikes.

I’m doing total drivetrain replacement on our two 2019 City’s and finding limited availability of the 46t 130BCD front chain rings. Some have pins and not sure if they will drag the guard. Some are for 9 speed chains and might be thinner. Has anyone just flipped these over before they were...
