Our Verdict: Rated 4.6/5
Ibis Oso Carbon from Ibis is a trail e-mountain bike with a Carbon frame, powered by the Shimano EP801 (85Nm). Carbon e-trail bike. Key strengths are DW-link, Shimano motor and carbon frame.
Specification summary: Shimano 630Wh battery with a quoted range of up to 90 km, Fox 36 Performance 150mm suspension, 29-inch wheels, SRAM GX Eagle 12-Speed, SRAM Code R 4-Piston brakes, weight 22.5 kg, price £6,348. At £6,348 it is about 13 percent above the typical e-bike price in the database, and at 22.5 kg it is in line with the typical e-bike weight in the database. The battery works out to roughly 28 Wh per kilogram of bike weight. Trail bikes balance climbing efficiency and descending capability, with moderate-slack geometry and travel that suits most terrain.
A full-power motor in the 85Nm class delivers strong assistance on steep, technical climbs at the cost of weight and battery consumption. Carbon frames offer a favourable stiffness-to-weight balance and can be tuned for compliance, though impact damage can be costly to repair. The 29-inch wheels roll over obstacles efficiently and carry momentum on rough ground. The mechanical 12-speed drivetrain offers simple, serviceable shifting with a wide gear range. Four-piston brakes provide stronger, more consistent stopping power for long descents. Range figures are manufacturer estimates; terrain, rider weight, assist mode and temperature can change real-world distance considerably.
Verdict: Ibis Oso Carbon scores strongly in this database with a 4.6 rating. It suits trail riding. Main caveat: expensive.
How We Rate
How we rate
Every rating on Gear Matrix is published alongside the information it is based on, so you can judge the score for yourself rather than take it on trust.
Gear Matrix ratings are editorial assessments built from published manufacturer specifications and comparative specification data. They are not presented as the result of physical product testing. Where an article is based on a first look, a launch announcement or a press release, the article says so.
Weight-to-power on e-MTBs
Where a weight-to-power ratio is shown it is calculated from two manufacturer-declared figures: the bike’s weight in kilograms and the motor’s declared output. Both inputs are required before any ratio is displayed. We never estimate a missing value, and we never infer a figure from a different model in the range.
The full breakdown of rating criteria is being prepared and will be published on this page.
