Small Frame Vespa  4kW Conversion Kit

Small frame scooters such as the Vespa Primavera are light and nimble making ideal electric scooter conversions. Fits all small frames 1963-1987 including PK These models can hold one battery.

£ 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. The kit comes with a single under seat battery and tray.

Our kit includes a DC brushless 4kW disc brake electric motor, sinusoidal motor controller, custom made swing arm, under seat battery tray and a single removable LG lithium-ion battery, along with a keyless ignition, battery gauge, all cables, LED headlight conversion and a charger. Additional batteries and chargers can be purchased separately.

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 new restoration with us.

During the build process we strip out the old engine and petrol tank , and install our kit as a direct replacement.

The 64v 26ah, 1800w battery is capable of up a range of up to 25 miles, ideal for your daily commute.

Our battery range is based on real world usage not hypothetical industry ranges. All batteries can either be charged onboard or removed for charging indoors.

The Vespa small-frame is one of the most popular vintage scooters ever made and is now available as a green, environmentally friendly form of transport with smooth, fast acceleration and a top speed of 55 mph.

All Project: E scooters are London ULEZ and Congestion Charge exempt as well as qualifying for free road tax.
