All Project: E electric powered scooters are exempt from UK road tax and emissions charges making it perfect for travelling in major cities such as London where the ULEZ means many scooterists are being forced off the road.  They travel about 5 miles for approximately 1 pence. Batteries can be charged onboard or simply pull out the battery when you get home, take it inside and plug it into any socket to recharge.

25 — 84 mile range

We offer a variety of battery options, each has been made specifically to suit a range of needs. Converted vintage scooters can hold from one to two battery packs depending on the model. Our range calculations are based on real world usage not industry hypothetical ranges.

INcredible performance

With a top speed of 65mph and smooth yet rapid acceleration, our Project:E fitted bikes are stunning to ride.

Shipping Rates

See our UK & International shipping rate estimates. All rates are based on kits with one battery.

a full conversion

We painstakingly designed and built this unique kit from scratch, choosing only suppliers that met the high quality and reliability we demand.  The conversion adapts the scooter throughout and includes modified electrics (like the LED headlight).

why buy an electric bike?

Here are a few more reasons why an electric scooter or electric moped makes so much sense these days.


As there is no petrol engine in this vintage electric scooter, they are zero emissions which helps you to do your part for the environment and reduce your carbon footprint and exempt you from any ultra low emission zones.

Easy to ride

There is no choke, no 2 stroke oil and no petrol station stops with a Project:E bike. Oh, and there is also no need for any gear changing either. The handling and manoeuvrability are also improved with the conversion.

Simple charging

At about 9kg, the batteries are easily removed for charging at home or at work. Batteries can also be charged onboard and spare batteries can be purchased separately.

low maintenance

With no moving engine parts, there is very little to go wrong in an electric motorcycle – making oil changes and expensive mechanical bills a thing of the past. Apart from brake shoes (or pads), cables and tyres, the wear is minimal.


All Project: E scooters are road legal and are similar to a normal 50cc or a 125cc. You can just twist the throttle and on you go, without the excessive noise and smell of petrol to worry about. Most are ridable after undertaking a CBT or car license but this depends on the date your license was issued.


All Retrospective Classic and Project: E scooters come with a full 6 month warranty, covering parts and labour.
