Solvay presents Kleefer’s Bud-e urban scooter with fairing parts in glass-filled Sinterline Technyl powders.

At the Challenge Bibendum 2014 event in Chengdu, Sichuan Province, China, Solvay presented “Bud-e”, a foldable electric scooter specially designed for intermodal mobility in urban areas and developed by French company Kleefer in close collaboration with Solvay Engineering Plastics.

The streamlined fairing parts of the scooter are made using the industry’s first glass-filled polyamide 6 powder for Selective Laser Sintering (SLS) from Solvay’s Sinterline Technyl range of materials. The technology delivers fully functional parts while offering greater design freedom as well as significant weight and cost savings over competing aluminum. Prior to the SLS process, the parts were optimized with Solvay’s MMI Technyl design for multi-scale modelling and structural analysis.

Kleefer, based in Lyon, France, develops and commercializes innovative light electric vehicles for the urban mobility market and has been partnering with Solvay since its foundation two years ago.

“Bud-e” is equipped with a removable, plug-in lithium battery pack that can be fully recharged in just 2 hours and gives the ultra-compact scooter an electric driving range of 20km at a speed of up to 25km/h. Together with a front hub motor, puncture-proof pneumatic tyres (200 mm diameter) and a reliable brake system it folds/unfolds in just 1 second and is the first of Kleefer’s “personal transporters” expected to feature Solvay’s high-performance PA technology. The electric scooter will be commercially available in 2015.
