Lambretta 4kW Conversion Kit

Lambretta Li/SX/TV series 1 to series 3 and GP models can be converted to battery power. This kit can hold up to two batteries and an additional charger.

£ 4,590.00 GBP

In conjunction with industry leading engineers, we have developed our own cutting edge technology that allows classic Lambretta scooters to be run purely on electric power. The scooter retains all its original styling features and the conversion is almost invisible from the outside. You get increased reliability, ease of riding and economy with electric power.

Our Lambretta electric conversion kit includes a DC brushless 4 kW electric motor, sinusoidal motor controller, custom made swing arm, large battery tray and top plate, a single removable LG lithium-ion battery, along with a keyless ignition, battery gauge, all cables, LED headlight bulbs 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 or simply the conversion to your existing scooter.

During the build process we strip out the old petrol engine,  and install our kit without doing any damage to the originality of the framework, all our conversions are totally reversable.

Lambretta Li/SX/TV models, 1, 2, 3 and GP models can carry our two medium sized 72v 29 ah batteries as well as a charger, giving a range of up to 70 miles.

Our scooter battery range is based on real world usage not hypothetical industry ranges.

When using two 72v 29ah batteries, both are used in parallel ensuring even power usage. We recommend carrying an additional charger with you ideally, two batteries and the charger has room seated in between the twin battery system.

Whether using one or two batteries, all batteries can either be charged onboard or removed for charging indoors.

Available for worldwide shipping with full instructions on how to fit this yourself or with the help of a local mechanic. Many of our kits are currently being shipped to the USA.
