What you have created is a bicycle in law and NOT a motor vehicle, so it does not need an SVA, VIN number or any other DVA approval before use, even with a thumb throttle and walk assist.

It can be ridden on cycle paths, but on shared use paths should be ridden slowly with due care in the vicinity of pedestrians.

If taking it to a test centre for a VIN or MAC for 250LPM, do not mention that if stopped since it might create suspicion that it is capable of more than the EAPC limits.

Bear in mind that police officers in general have a very poor knowledge of our cycling and EAPC law so there is never any guarantee of not being stopped or even having a legal bike confiscated temporarily. It's a risk we all have until the current hysteria about e-bikes abates.

These are the requirements for an electrically assisted bicycle that doesnt need registration, insurance, licence, etc:
1. Max motor speed 15.5 mph
2. Motor must be rated at 250w or less
3. The bike must be able to be pedalled when switched off.
4. The power must stop when you stop pedalling
5. The bike must be marked with a label that shows manufacturer, motor power and max assisted speed.

You can avoid number 4 by getting an SVA test, but then you must comply with all relevant motorcycle construction and use regulations such as lights, indicators, mirror, ball ends on the levers, stand, electric cables protected, etc.

LPM 250w category doesn't require indicators, don't see them on Wisper bikes.
Do lights have to be fixed wired ones ?

Hi Neal,

You are correct, there is no requirement for indicators, or mirrors. The lights have to be wired into the bike battery and both front and rear must turn on with the same switch.

All the best, David

For a light switch I would use a dual wuxing 22mm handle bar mounted one .
Buy a 6v - 60v front wired light which has an integrated horn and buck converter and a 36v/60v rear red light both in parallel. Take the sW power supply from the battery to controller power supply . Add an inline covered blade fuse on the V+ power supply line.

When I was commuting this is what I did never had to bother with charging separate lights as one always had power for them from the bikes battery.
My rear light was as bright as a rear fog light, on ecan get them for about £3 - £5.
