As one of the world's leading scooter restoration businesses we have worked with expert engineers to create a set of bespoke kits that allow most classic Vespa scooter to run 100% on electric power. No more petrol, no more two-stroke oil, no more smoke and no more gear changes. Just clean smooth electric power.

Our wide mount Vespa kit includes a modern DC brushless electric motor, sinusoidal motor controller, custom made swing arm, engine side battery tray , single removable LG lithium-ion battery, along with a keyless ignition, battery gauge, all cables, LED headlight conversion and a charging cable.

If you wish you can add another battery to your kit or you can order one at a later date.

We offer this as a conversion to customers who already have a suitable classic scooter or as an engine option to customers who are looking to carry out a new restoration with us. You can also order the kit and fit it yourself or get a local garage to do it for you.  We also ship the kits worldwide and have customers all over the world and especially in the USA.

During the build/restoration process we strip out the old petrol engine and install our kit as a direct replacement for the petrol engine.

Vespa wide-frame models can carry one 64v battery under the engine side panel and a second 64v battery under the left hand side panel.

With two batteries installed a range of up to 50 miles can be achieved. This range is based on real world usage not hypothetical industry calculations. When using two batteries, both are used in parallel insuring even power usage. Whether using one or two batteries, all batteries can  be charged onboard or the engine side battery can be removed to charge off the scooter.

Please note: On this model the second left sided battery is not removable.

Further note: All wide mount VESPA GS 150 models can carry our larger 72v 35ah batteries giving further increased range and performance. We can discuss this with you when you order.

To find out how the kit works and how it is installed, take a look at our selection of helpful YouTube demo videos.
