Large Frame Vespa 4kW Conversion Kit

Once converted, large frame Vespas have the power roughly equivalent to a modern 125cc engine. These models can hold one or two batteries. Fits all L-Frames 1958 - 2018 including the PX range .

£ 4,390.00 GBP

In conjunction with industry leading engineers, we have developed cutting edge technology that allows a wide range of classic Vespa scooters to be run purely on electric power. The exterior styling remains totally original whilst ease of riding, reliability, economy and environmental footprint are all brought into the 21st Century.

Our electric scooter conversion kit includes a DC brushless electric motor, sinusoidal motor controller, custom made swing arm, battery tray and a single removable LG lithium-ion battery, along with a keyless ignition, battery gauge, all cables, LED headlight conversion and a battery charger.

For extended range a second battery can be added at checkout or purchased separately at a later date.

We offer this as a conversion to customers who already have a classic scooter or as an engine option to customers who are looking to carry out a scooter restoration with us.

During the build process we strip out the old petrol engine, and install our kit as a direct replacement. The Vespa large frame kit comes in two variations depending on the intended model to be converted.

You can also order this online and we will ship it worldwide with full installation instructions that you or a local garage can follow.

Vespa large-frames can carry a choice of three battery sizes
- Large 72v 35 ah battery  40 mile range £1395
- Medium 72v 29 ah battery 30-35 mile range £1195
- Small 64v 26 ah battery 25-30 mile range £995

A second battery can be added under the left side panel for double the range which must be of equal specification, as it will run simultaneously.

Depending if the left side panel is either the classic "glovebox" version, the second battery will be a non removable small or large version. those Vespa's with the spare wheel under the left side panel will have the choice of all three batteries but this incurs the frame modification of the spare wheel bracket removed.

This range is based on real world usage, not hypothetical industry predictions. When using two batteries, both are used in parallel insuring even power usage. Whether using one or two batteries, all batteries can either be charged onboard or removed for charging indoors, except if you have a left side panel battery with toolbox panel.

You can watch lots of practical information and installation guides too (if you are thinking about this as a DIY project) on our YouTube channel.
