Riese Und Muller is named after the 2 founders, engineers. Mr Riese and Mr Müller invented the Birdy, which became worldwide famous for its fully suspended folding bike technology in the 90's. Using their knowledge and expertise, they took the challenge of e-bike technology very soon and developped fully suspended e-bikes (the Riese Und Muller signature). Their confort and performance put them on top of the performance reviews (such the Eurobike award on 2015 for the Charger GX), and ensures great confort for the user. They are also developing edge cutting technology for speed-bikes !
