The last monthly magazine of the UK motor home club that I belong to published a rather scaremongering item about electric bikes. Essentially, it was a copy of an item from Motor Cycle News where someone who was involved in an accident was to be prosecuted for having an an illegal spec electric bike.
So I want to send them a myth buster response, because there's no doubt that the original item would put people off buying. Below is my attempt at listing the key requirements based on research around the various sites. If anyone, especially the dealers, spots any errors or misinterpretations in this piece, please let me know.
I did search for a Fact Sheet from the DoT that I'd seen mentioned, but didn't find it. So again if anyone has a working link to that, I'd be grateful.
Here's my summary piece:
"1. The rider must be aged at least 14
2. The electric bike must not be capable of exceeding 15 mph while under power
Of course, you can ride as fast as you like when the motor is not providing assistance, for instance when freewheeling downhill, but you must still obey traffic laws. Most electric bikes are configured so that the power automatically reduces as speed increases and will cut out completely once a speed of 15 mph has been reached. Not only does this help comply with the law, it makes sense to reduce any unnecessary use of the battery.
3. The electric bike must not weigh in excess of 40kg for a bicycle, or 60kg for a tricycle
4. The continuous rated power of the motor must not exceed 200 or 250 watts
In general, the limits are 200 watts for a bicycle and 250 watts for a tricycle or tandem. There have been different interpretations of this requirement. For example, the European limit for bicycles is 250 Watts. As a member of the EU, this limit should apply to the UK also. However, the older 1983 UK legislation is 200 watts for bicycles. So, as in any decision you make based on an interpretation of the law, it’s usually better to play safe and work on the 200 watt limit for a bicycle.
5. The motor alone cannot be used to propel the bicycle, so power can only be brought in while the rider is pedalling
Again, with this requirement there is some disparity between the 1983 UK legislation and the 2002 European rules and you should err on the side of safety. This time, it’s the European law that is the more restrictive and doesn’t allow the cycle to be propelled using power only. In reality, this requirement is met as long as the pedals are rotated (no matter how gently you pedal or how little physical effort you put into those rotations). The UK’s Construction and Use Regulations on this aspect state that the power assistance must default to Off – meaning that some minimum pedalling intervention from the rider is needed in order to maintain power assistance."
