German startup Lemmo has developed the Lemmo One, an innovative e-bike that features a unique motor-releasing clutch mechanism. Unlike traditional e-bikes where the hub motor remains engaged, creating resistance when pedaling, the Lemmo One allows riders to uncouple the motor from the hub for easier manual pedaling.
At first glance, the Lemmo One appears to be a regular human-powered bicycle. However, it comes equipped with a 250-watt rear hub motor that produces 40 Nm of torque and a frame-mounted Smartpac that houses the 540-Wh lithium battery, motor controller, and other electronics.
In e-bike mode, riders can select their desired level of motorized assistance by simply pressing a button on the handlebars. The motor kicks in as needed, propelling the bike to a top assisted speed of 25 km/h (16 mph). With a single charge of the battery, riders can enjoy a range of up to 100 km (62 miles).
When riders prefer to pedal without any motor assistance, they can remove the Smartpac and activate the clutch mechanism located on the rear hub. This disengages the motor, eliminating any mechanical resistance and making pedaling significantly easier.
Additional features of the Lemmo One include a powder-coated welded aluminum frame, a carbon fiber fork, integrated lighting with a removable headlight that doubles as a flashlight, a 100-decibel theft alarm and GPS tracking, a down-tube-integrated LCD display, hydraulic disc brakes, and a Shimano Deore 1 x 10 drivetrain. A belt-drive option is also available.
The Lemmo One weighs around 15 kg (33 lb) without the Smartpac and an additional 3 kg (7 lb) with it, resulting in a total weight of 18 kg (40 lb) in e-bike mode.
Pricing for the Lemmo One starts at €1,090 (approximately US$1,184) for the base bike, with an additional €900 required for the Smartpac, bringing the total e-bike price to €1,990 ($2,161). The Smartpac can also be rented, although this option is currently available only in Berlin.
The Lemmo One offers cyclists a versatile and convenient e-bike option, allowing them to switch seamlessly between motorized assistance and manual pedaling. Its motor-releasing clutch mechanism sets it apart from traditional e-bikes, providing riders with a smoother and more enjoyable riding experience.
