E-Bike with composite chassis made of two half shells

摘要

An nCycle e-bike frame includes two corresponding half-shells (1) and (2) which include an auxiliary cavity (1a) and (2a), battery hatch cavity (1b) and (2b), motor housing cavity (1c) and (2c), seat post column channel (1d) and (2d), steering column channel (1e) and (2e), steering column stopper (1f), rear fork (1g) and (2g), rear hub mounting (1h) and (2h), brake caliper mounting points (2j), outer membrane (1k) and (2k) and internal ribs (11), (21). A locking system comprised of two sliding pistons (29) and (30) and a locking mechanism (31) can be added. The crank electric motor (25) and battery (24) are enclosed between the two half shells (1) and (2), thus providing a smoother and safer structure for the rider. The integrated locking system and auxiliary hatch make the frame more flexible and easier to use compared to previous implementations.
