A friend has an ecoco that won't go faster than about 14kph. The battery indicates full charge. Thoughts?

Actually my hub is the bomb, I've hit it with my full power plus full Ultra throttle and it didn't blow up time after time. The issue arises because when I pause to shift then hammer my pedals, engagement is abrupt and things break. Once a few teeth were smashed it was only a matter of time...

I had it all "reassembled," taped up and stuffed in a box before I saw the photo request, I'll take some photos when the parts arrive & I put it back together.

Don't know about the USA but I know they're available in Canada. I have a Fat Integra in Vernon BC. Fun bike. My only issue was with the battery connection but I've decided a few seconds on the end of a winter ride is liveable, If I'm going riding I already have the tool on me so no big. I've...

I don't know which gen it is. I assume UART. I reprogrammed it a couple months ago to a "someone's smooth tune" I found here but the damage was already started. The damage was because as I was pinning it to get to a reasonably safe traffic speed (throttle is one of the best safety features of a...

No dirt ingress. It was all clean and greased with the exception of all the metal bits that smashed off and were floating around. It wasn't a bearing issue, the notches that the pawls click into to engage the cranks are smashed off. Surprisingly the pawls look fine, the leading edge may be a...

Update in case anyone has a similar issue. I had complete failure on the way to work this morning. I stood on the pedals and something went snap, I could pedal all I wanted and go nowhere but the motor still engaged under throttle so I wasn't walking. I got to work and ripped the motor apart...

Yes, I believe you are correct. Know any good sites for parts? The google? Amazong?

Well no s*it.

Drive sprocket does not turn. Cranks turn with no resistance

I have an ultra in front of a Rohloff hub. I pause pedalling to shift then hit the pedals again. Doing this repeatedly under heavy acceleration is probably not the best for my drive but it happens. The issue that has developed is that my cranks don't engage for almost 1/2 rotation. I haven't...

It is the cradle for the button pad, not the cradle for the display. Not sure where the problem is, options are: busted wiring at cable connector pins, busted wiring along the length of the cable, broken connection within the cradle itself. The cradle is not openable other than by destructive...

Anyone know I'd find one of those?

The owner of the bike found another identical bike so I was able to pinpoint the problem.

Every connection cleaned. all spring pin connectors springing. all cable connections checked ( and pins on connectors). all the pins and pin pads polished with emery cloth

I would have guessed that has a battery it obviously has a battery cover. I popped this one apart, there is no battery within.

It is a removeable display, once removed there is no way to unscrew the display to separate the front from the back. There is no indent where a screwdriver might be used to pry it open.

No apparent way to separate the display case so I'm thinking thats unlikely.

Ya, pulled the controller and checked all connections.

The bike, Easy Motion Evo Pro The display indicates there is a 0% battery and the battery symbol is flashing, there is an exclamation mark in a triangle all flashing and the dreaded Err:13. Checked every connector, Checked all spring pins on display & battery connection cleaned all connection...
