According to Maxon, the BIKEDRIVE Air e-Bike system weighs only 3.5kg (including the battery). Moreover, the e-Bike #middrive is almost completely hidden, as well as the 250Wh battery that’s concealed in the downtube, while the range can also be doubled courtesy of an additional battery https://capovelo.com/maxon-brings-mechanical-doping-to-the-masses-with-new-invisible-bikedrive-air-e-bike-system/

One of the world’s leading manufacturers of #e-Bike drive system, Bafang introduced new H700 automatic dual speed Rear drive system. With a weight of 3.2kg, the H700 rear motor with 250W rated power and 32Nm of torque it can easily ensure a strong performance for riders in daily commuting https://www.bike-eu.com/products-innovations/artikel/2021/08/bafang-launches-h700-built-in-automatic-dual-speed-drive-system-10141154

Baumeister GmbH has developed new mid-drive motors up to 140Nm with integrated continuously variable transmissions. The drive-system will be offered as a Pedelec version (25 km/h) or as an S-Pedelec version (45 km/h) and has a bottom bracket with built-in double gear, which should have a diameter of 75 mm https://pedelec-elektro-fahrrad.de/news/baumeister-praesentiert-mittelmotor-und-nabenantrieb-mit-ueber-1000-spreizung/594121/

Supercapacitors have one big advantage over batteries – they charge much faster. But they also discharge energy more quickly, limiting operating range. Engineer Tom Stanton built a supercapacitor pack and drive unit for an E-bike to see just how it stacks up to battery power https://theawesomer.com/making-a-supercapacitor-electric-bike/641139/

And why not integrate transmission into the #eBike motor, when the latter is located in the hub? This would save space, weight, simplify the whole. The Accel Group has embarked on this technical challenge. Baptized SA IHG, transmission is planned with an internal 5-speed gear and a 40 Nm electric motor https://www.breezcar.com/actualites/article/innovations-technologiques-velos-assistance-electrique-0217

An #ebike fueled with hydrogen instead of electricity? Florian Freund developed a prototype with which the hydrogen e-bike can be refuelled safely at the H2 filling station. A tank filling of 33 grams of hydrogen gas should allow a range of more than 100 km https://phys.org/news/2018-04-hydrogen-aid.html

FreeFlow Technologies (FFT), a Scottish company says that developed the world’s lightest power to weight #eBike mid-motor, allowing riders to travel faster and further for less effort. In developing the company’s design team has registered three patents in 15 countries, with a further five pending https://cyclingindustry.news/pint-sized-freeflow-technologies-motor-begins-oem-sign-up/

German company Schaeffler has just revealed an innovative new drive system for electric bicycles that eschews traditional bike chains and belts. The rider’s pedaling action powers the generator and converts the energy from mechanical to electrical energy. This “bike-by-wire” system is all controlled with CAN communications between the motor, battery, generator, and control electronics https://electrek.co/2021/08/31/radical-new-electric-bike-drive-systems-requires-no-chains-or-belts-entirely-ride-by-wire/
