I remember being told back in 2010 that when my first conversion was done I should take it to a 'testing centre' to see if it's OK.
Now here's the daft thing, the company Cyclotricity who I had my very first eBike off use the same parts as Yose Power which are the parts on my eBikes.
However Cyclotricity have a license to put those parts on really bad bikes that you'd pay £100 for from Sports Direct where my bikes are quite good ones.
Here is a recent picture from a Cyclotricity group of a Stealth bike, the one I had in 2010, that was a piece of junk but they have a license to put parts on it.
the bloke broke his arm.
Obviously they want to sell you a ready-made e-bike, but they do state that conversion kits are legal if within spec. As you'd expect.IS IT LEGAL TO CONVERT MY BIKE INTO AN ELECTRIC BIKE?
Cyclists who already own a road, mountain or other 'ordinary' cycles may consider a conversion kit so they can ride an electric bike at higher speeds without purchasing a new model. Kits can help to retrofit an electric motor to your bike. Many eBike conversion kits are legal, however it can be difficult to know how to make sure any engines or parts you fit are complying with the legal rules and regulations for electrically assisted pedal cycles.
While you can in effect make your own eBike using a conversion kit, it’s not typically recommended - it’s generally quicker, easier and more efficient to purchase a ‘ready made’ electric bike that you can be sure complies with UK law around pedal assist, maximum speed and battery power.
There's certainly a market for buying good well made secondhand bikes from Gumtree etc, converting them into e-bikes using a reliable legal 250w conversion kit and then selling them on to cyclists

Now where is that de limited top speed option on my BK6
Ebikes don't seem to be a huge issue yet (except for randomly exploding and burning houses down). But I've seen so many near missed caused by people on scooters, including basic dumb stuff like just suddenly darting out across the road without looking.
Also if you clip anything with the front wheel like a curb, pothole, big stone, maybe a bottle, you will face plant the floor immediately and need new teeth.
25 mph is the max settings for the BK6 uk version.
Disclaimer: I might be talking out of my bottom.
I've been thinking about this a bit more.
From what I've read, the Bafang and Tongsheng motors are all the same, with the exception that the 36V and 48V variants are geared differently.
But the 250W, 500W, 750W and 1000W motors are the same.
What determines the motor's output is twofold:
* The battery management system of your battery. This determines the maximum current that the battery will output before shutting down for safety.
* The LCD controller, which determines how much current the motor is given (assuming the battery can/will provide it). The controller governs all aspects of the motor's behaviour.
Chester police may be saying that the Bafang/Tongsheng kits aren't compliant, because there is no restriction in the motor itself. The restriction comes from the LCD controller, and this is software (and can be overridden).
I am not sure if e-bikes (not converted) have actual circuitry in the motors themselves to limit their output? Perhaps this is the key distinction.
So that then begs the question: Why does it matter if the motor is restricted by software or by hardware, if it is restricted within the law?
thanks for the pointer, registered and will lurk around for info
I had a kid on an electric 'stand on' scooter keeping up with me from a set of traffic lights, up to 55mph (single carriageway), wearing just a hoodie (no helmet).
Quite a shock seeing him in the rear view mirror, almost touching my rear bumper at that speed. He went around a large motorway island, through red lights, and disappeared from view.
I didn't realise those type of scooters could go so quick.

not sure why an e-bike is any more susceptible to pot hole damage than a regular bike, apart from a bit of extra weight
