Honda RN0 Electric Mountain Bike Unveiled (Nov 2026)

Honda showed the RN0, its first high-end electric-assist mountain bike, in a world premiere at EICMA 2026 in Milan on 3 November 2026. Honda says it developed the bike with ROTWILD, a German maker of electric mountain bikes. The company lists a weight of about 24 kg, a Shimano drive unit with 100 Nm of torque and 750 W peak output, and a 720 Wh battery. Honda's pages do not give a price or a sale date. Details are as of 4 November 2026.

What "electric-assist" means

An electric-assist mountain bike, or e-MTB, still has pedals. The motor adds power only while the rider pedals, and the battery capacity, measured in watt-hours (Wh), is a rough guide to how long that help can last. The 720 Wh figure is Honda's battery capacity. Honda's pages reviewed here do not state a range, because range depends on the rider, the terrain and the assistance level chosen.

How pedal assist generally works

The following is general background from a reference article on electric bicycles, not a statement about the RN0. A bike with pedal assist, often called a pedelec, only helps while the rider pedals. Sensors measure how fast or how hard the rider pedals, or both, and the controller sets the motor output to match. The article says that bikes from the 2020s commonly use torque sensors, which give smoother power delivery.

Electric mountain bikes often put the motor near the pedals, a layout called a mid-drive. Because that motor drives the chain and the bike's own gears, the same article says mid-drive power is usually limited to roughly 250 to 500 W to reduce wear. Honda lists the RN0's maximum output at 750 W, so it quotes a peak figure; it has not said what continuous rating applies.

Rules that differ by country

In the European Union, the standard EN 15194 defines a pedelec as a bike whose motor helps above 6 km/h only while the rider pedals, cuts out at 25 km/h, and has a maximum continuous rated power of 250 W, though it may briefly exceed that. Honda's pages do not say which legal class the RN0 will fall into in any market, and rules in other countries can differ.

The same article notes that range depends on assistance level, battery size, speed, hills and the combined weight of bike and rider, and gives about 40 to 120 km per charge as a typical spread for e-bikes in general. Honda has not published a range for the RN0.

Honda's e-MTB entry in Europe

Honda's European press release describes the RN0 as an all-new electric mountain bike and Honda's first entry into the European e-MTB market, and lists it among its key announcements for 2027. It names ROTWILD and Shimano as development partners.

The mixed wheel size

The bike uses a larger 29-inch wheel at the front and a smaller 27.5-inch wheel at the rear. Honda lists the sizes but does not explain its reasons in the pages reviewed here.
