Orbea Rise SL M20

The Orbea Rise SL M20 is built for riders who want assisted climbing without losing the light, flickable feel of a proper trail bike. Its carbon Rise SL frame keeps travel modest by e-MTB standards, at 140mm out back and paired with 29-inch wheels, so it behaves more like a well-sorted analogue bike that happens to help you up hills than a power-first machine built purely for descending. If you already ride trails for the fun of cornering and popping off features, and simply want more climbing and more laps in a day, this is the kind of bike built with you in mind.

A trail bike first, not a mini descender

Orbea also builds a Rise LT, a separate model with longer travel aimed at bigger descents. The Rise SL you're reading about here is a different proposition: its 140mm of rear travel and the geometry that goes with it are tuned for quick-handling trail riding rather than rough descending, so it's worth keeping the two apart when you're comparing options rather than treating them as two versions of the same bike.

How the motor delivers its help

Power comes from a Shimano EP600 RS Gen2 motor, which Orbea tunes with two distinct settings: RS, said to deliver up to 60Nm of torque, and RS+, said to deliver up to 85Nm. The bike is delivered set to RS+, so you get the stronger assistance from the first pedal stroke, with the option to wind things back to the gentler RS setting if you'd rather feel more of your own effort on easier days.

Picking between the 420Wh and 630Wh battery

The M20 comes with a choice of two fitted internal batteries: 420Wh or 630Wh. The bigger battery simply stores more energy; it doesn't come with a fixed mileage promise, because how far you'll actually get depends on terrain, assistance mode, rider weight and conditions on the day. If you want more capacity later without buying the bigger battery from new, Orbea sells a 210Wh RS Range Extender separately; it's an optional accessory rather than something fitted as standard, so don't assume a listing's total capacity includes it unless the seller says so. You may also see this exact bike listed under 2025 or 2026 labels, or grouped by colour; those labels don't indicate a different frame or motor here, only the battery you choose does that.

Suspension, gearing and brakes built for the job

Both battery builds share the same running gear: a FOX 36 SL Performance GRIP fork and FOX Float Performance two-position shock, matched to the frame's 140mm of travel; a Shimano SLX 12-speed drivetrain with a wide 10-51-tooth cassette and 32-tooth chainring for steep, assisted climbs; Shimano M6100 hydraulic disc brakes; and Race Face AR 30c tubeless-ready wheels. There's also an OC Mountain Control MC22 dropper post fitted as standard, so you're not left buying one separately before you can drop the saddle for a technical section. Together, this is a specification built for actual trail use rather than a base build waiting for early upgrades.

Sizing and geometry across S to XL

The Rise SL frame is offered in four sizes, S through XL, each with its own published reach, stack, head and seat angle, chainstay and wheelbase figures. Orbea hasn't published a height or inseam chart specifically for this model, so treat any generic retailer sizing chart with caution; the geometry figures are the reliable way to check reach and stack against a bike you already know fits, rather than relying on a height range alone.

Because the SL keeps its weight and handling close to an unassisted trail bike, it's a good fit for someone who wants to keep riding technical singletrack the same way they always have, just with extra help finding the top of the next climb.
