A traditional mechanic pedal bike easily lasts for 15 years. In the electric drive system and IoT, developments are still ongoing. This typically results in a much shorter life span of E-bikes. The LEMMO separates 'the e-parts' from the bike itself, by integrating the controller and IOT in the detachable SmartPac and adding a mechanical clutch to the hub motor. This concept leads to 3 unique advantages: (1) Sustainability: the bike can be ridden longer while only the tech (smartpac) gets upgraded regularly or replaced when required. This dramatically increases the lifespan of the bike over regular E-bikes. (2) Usability: the concept allows you to have a mechanical bicycle and an E-bike within the same product. This allows for very different use cases: a super comfortable electric commute and a smooth human-powered sporty bike ride on the weekend. (3) Financial options: this setup offers more diversity in purchasing options where people can combine, buying bike only and rent a battery, buy together or buy bike only and battery later, at any time. Main components: (a) Dual Mode hub: The highlight of the LEMMO One is the 250W hub motor, which can be completely disconnected from the drivetrain. This turns the E-bike into a conventional bike of only 15kg - without the additional weight of the battery and without motor-related pedaling resistance. (b) Smartpac: Besides supporting very different use cases, the LEMMO One also addresses another very important aspect of E-bikes. Where traditional bikes easily have a lifespan of 10-15 years, the electric drivetrain technology (mainly controller, battery pack and battery management) is still developing and improving every few years. This result is a great improvement of the E-bike's lifespan as a whole, compared to other current offerings, and further improves the product's sustainability and positive impact.. An all-in-one pack, Smartpac is the brains of LEMMO ONE. In addition to the bike's battery, it houses all electric systems outside of the frame, including the motor controller and IoT device. Each is interconnected by a CAN bus network, a robust standard that allows microcontrollers and devices to communicate with each other's applications without a host computer. The Smartpac supports 4G networks, GPS tracking and FOTA for wireless updating of the system. The Smartpac can easily be updated every few years (even in a subscription program), keeping your LEMMO One up to date always. Taken from the bike, the Smartpac can be used as a power bank for all your mobile devices. (c) Frame: The beautifully smooth aluminum frame (available in a regular and a step-through version and 2 sizes) features a new advanced, no welding technology, introduced from the automotive and aeronautical industry, resulting in a super smooth result. (d) Hub lock: A nicely hidden electronic hub lock protects the LEMMO One against theft, and allows for shared use with your family and friends.Using innovative production techniques, the frame is beautifully sculptured, with a top tube fluently opening up around the seat tube and meeting up with the rear axis. In front, the top tube and down tube tightly embrace the SmartPac, which connects through a latch in the head tube. Frame and SmartPac thus form an elegant and natural combo. The LEMMO One is elegant but confident. It is both comfortable and sporty. Two faces, one soul.
