Dear oh dear! The story is that Hunter Biden's laptop was put in for repair in 2019 and the repair guy cloned the hard drive and handed it to the FBI, who've been sitting on it all this time. The contents are now in the public domain. The emails shown, indicate to me that Joe Biden was involved...

I think you're misunderstanding me. I'm talking about using a hub-motor without spokes mounted in the middle of the bike to drive the chain, like this, but with a motor instead of a jackshaft:

Hopefully, it's something simple, like you've pulled the motor connector a bit, so it's not making good contact. It has to go all the way in until the edge of the outer reaches a line around the other side. The mosfets only blow when you give full power via the throttle or PAS while the motor...

There's a whole range of motors you can use. One method is to use a hub-motor. Mount it on a couple of drop-outs (drop-ins) in the middle of the bike. If you use a rear one, you put a cassette or freewheel on it and use two of the gears: One with the chain to the crankset and the other going...

A bottom bracket motor will put about four times as much force through the crank compared to what you presently have. Are you sure the frame and fixing of the BB are strong enough?

Here's how to work it out if you're any good at Laplace transforms: https://dademuch.com/2018/12/28/mass-spring-damper-system-dynamics/

You can't fit a downtube battery to a carbon fibre frame, as Kudos found out. He can fit a rear motor if he has a metal rear subframe, though I can see two problems. Firstly, the subframe top bearings look very vulnerable to any attempt to stretch the frame to get a cassette motor in, depending...

My honest advice is not to do it. Sell that bike, then either buy a ready-made ebike that suits your needs or buy an older bike with a metal frame to convert to how you want it. Without knowing what you want and what you want to use it for, it's not possible give any more specific advice.

If the code is correct, the most likely logical cause would be blown mosfets in your controller. What were the circumstances leading up to getting the error code? When you say, "keeps coming up with", do you mean that it does it every time you switch on and the bike never works? Where from did...

It reminds me of an incident about 10 years ago and ebikes were quite rare. I had installed a kit on mine with the controller and battery in a bag behind the seat. I passed a guy struggling up a steep hill just before some red traffic lights. He came up alongside me and said, "You made that...

Topbikekit are a good company, but like many Chinese suppliers, they struggle with the English language. There are lots of suitable controllers, but you haven't given any details of your bike, how much power you need, what battery you have and what current your present controller allows. The...

I just read that Guardian article from May that was mentioned above. Some of it isn't bad, especially for those that don't know about ebikes. https://www.theguardian.com/lifeandstyle/2020/may/17/i-can-just-glide-through-traffic-how-e-bikes-could-answer-our-commuting-problems If you wanted to...

https://www.18650batterystore.com/21700-p/lg-m50.htm The spec for the cells is 7.3 amps max continuous x 2P = 14.6 amps. The spec for the battery, which uses those cells is 20 amps max continuous. Hello! What controller are you going to use?

You need a chain drive kit, which seem to be a bit thin on the ground these says. I found this one from Cyclone. Eclipse bikes are agents for Cyclone, so it might be worth talking to them. http://www.cyclone-tw.com/doublefreewheel.html

These type of clutches are more or less sealed against water, unlike the AKM/Q-series motors, which are open and have tiny springs that go rusty and jam the rollers. I've had a jammed clutch a couple of times on Bafang motors, probably for days or weeks before I noticed. Most can be sorted by...

All controllers will work with your motor. They have different performance characteristics. You have to tell us what you're trying to achieve. That looks like an OEM controller. It won't be easy to find an identical one. Are you OK with wiring and soldering? The 9pin connector is standard, but...

If you're serious about needing help, you need to provide proper photos of your bike showing all the details of the wheels, frame, bottom bracket and gears.

When installed, check that the rim is central to the frame. You might need to dish the wheel to get it in the centre. When installing the wheel and you have a disc brake, get your spacing right from the disc side first. You need to make sure that the disc lines up with the caliper, which nearly...

The clutch doesn't affect the wear on the cogs. All it does is let the motor freewheel. If it jams off, you get no drive. If it jams on, most people wouldn't notice. All it does is keep the motor engaged, so you get a little more resistance during freewheeling. The load on the gears in that...
