What are the vehicle regulations UK?

Look up the I.V.A. (Individual Vehicle Approval) regulations on the web, or go to your local V.O.S.A. (Vehicle and Operator Services Agency) offices and ask.

You'll find that in reality, what you want to do is very expensive and utterly impractical. You cannot legally just build a vehicle and put it on the road, even if it is electrically powered.. There is much, much more to it than that. Which is precisely why you don't see the type of vehicle you want to build, on the road.

You can certainly do this but it's not going to be easy for a beginner. To use the vehicle on the road (Road Legal) it must be built to conform to the Construction and Use Regulations and the The Road Vehicles Lighting Regulations; then inspected and certified by the DVLA.

It doesn't matter whether the thing is powered by an electric motor or a petrol/diesel engine, the rules apply. That's why the law refers to "mechanically propelled road vehicle" - it covers anything that does not use human or animal power.

It's not as easy as "put lights and indicators on it and stuff". The lighting must be very carefully positioned on the vehicle, not just stuck on where you think you want them.

The "stuff" must include things like pedestrian protection, crash worthiness, mirrors, speedometer, mudguards (wings), bumpers, brakes, mirrors, fireproofing, protection of electrical components, etc. All of these must conform to the Regulations. If you get it wrong you will never be able to insure or tax the vehicle.

You can find the regulations on the web site www.legislation.gov.uk. They are written in reasonably clear English but there is a lot of them and they're extensive and complicated. So you'll have to read the law very carefully to extract the parts that apply to you. Once you have found the sections that apply to your car you must build it to match these specifications.

When you have built the car you must contact the Driver and Vehicle Licensing Agency to arrange an inspection so it can be approved before being insured and issued with a tax disc.

Links to the law (Statutory Instruments) in the box below.

The bike: not legal. Electrically assisted bikes are restricted to ~240 watts ie1/3 hp, 15 mph, and power only when assisting pedals. Max weight regulation also.

If you build it as a motorbike or gokart then has to meed Construction and Use regulations, and pass a SVA inspection. Home builds certainly will not pass this. Even recognised kit cars can fail if not built exactly to spec

As with all road going electric vehicles you are limited either by:

a) The length of the power cable.

or

b) the weight of the batteries needed to give you adequate range.

That's even before you get into C&U regulations.

not straight forward .previous advise is good.

all transport on road needs type approval and has to meet certain criteria. eg sharp edges .turning circle limits, lights. horn and so on.

will need insurance possibly.

no reason we cant build it. wet battery is not good for bicycle use. dry better . electric bikes already on road so not much chance of sudden assistance with that project. go kart will have limitedappeall sadly. good luck though

Somewhere, there is the UK Motor Vehicle Construction and Use Reglations. I used to have a copy. Maybe you can find it online.
