Romanian e-mobility startup Diodra is laying declare to creating the world’s lightest ebike with a bamboo body. The S3 suggestions the scales at 15 kg (33 lb) and options an all-in-one hub drive that features motor and battery.
The place many ebikes are constructed round an aluminum body, some roll with magnesium alloy and others might boast carbon fiber, Diodra has opted for sustainable, light-weight and powerful bamboo. The laminated bamboo has been bonded to an aluminum head tube, whereas an aluminum seat tube slices by the mid-section and ends in a backside bracket.
The body is weatherproofed with a “two part coating system” plus three layers of varnish, and the ebike’s makers promise “distinctive vibration absorption, leading to a remarkably snug experience not like something you have ever skilled.”
Machined dropouts to the rear enable for adjustable chain pressure and precision brake alignment. And the fashionable aesthetic is not spoiled by unwelcome cabling flapping about, as such issues are routed internally to take care of clear traces.

The S3 is being made in Europe, which has restrictions on allowable steady motor output for ebikes. Which means that although the brushless rear-hub drive is rated for 500 watts, it has been restricted to 250 W. We’re undecided if that cap will stay in place for US consumers, however we do know that prime pedal-assist velocity past Europe’s attain is locked to 32 km/h (20 mph).
A torque sensor is cooked in for a extra pure, responsive really feel to motor help over three ranges, and digital gear shifting has additionally been included for “seamlessly delivering the mandatory energy for varied situations.”
You might have seen the shortage of a battery on the attractive body, and it is because the 300-Wh Li-ion battery is enclosed in the identical housing because the hub motor. There is not a throttle right here both, and per-charge vary is given as greater than 100 km (62 miles) on the lowest energy degree.
Actual-time monitoring and settings tweaking may be undertaken by way of a companion app working on a Bluetooth-paired smartphone, together with on-line downside analysis, navigation aids and “social options.” Rounding out the important thing specs are 28-inch DT Swiss alloy wheels wrapped in puncture-proof Continental Contact Velocity tires. Stopping energy is offered by Shimano hydraulic disc brakes.

“The creation of the bikes was a fancy and demanding journey that concerned a few years of analysis, growth, and overcoming failures,” stated firm founder, Sabin Dimian. “Actually, I’ve misplaced depend of the variety of occasions we confronted setbacks whereas striving to create a motorcycle that’s sturdy, light-weight, and low-maintenance. However in the long run, we succeeded, and I am extremely proud that we by no means gave up. We developed these bikes to satisfy the wants of at the moment’s city commuters.”
The Diodra S3 is up for pre-order now beginning at US$2,399. A non-ebike M8 model will also be had for a pre-launch value of $1,699, which rides with a Shimano Alfine 8-speed geared hub. Both method, an non-compulsory improve to a Gates Carbon belt drive is out there, in addition to non-compulsory equipment corresponding to fenders and lights.
