The Orbea Gain already offered one of the most sleekly integrated, stealth e-bike setups when it debuted three years ago. Now, Orbea is back updating the same popular and versatile e-bike platform, giving the 2021 e-road Gain a top-spec OMR carbon overhaul, fully internal cable routing, and even neatly integrated lighting – all with the same proven 250W Ebikemotion hub motor and 250Wh battery hidden inside the downtube.

The Orbea Gain was one of the early adopters of the less-torquey, more minimalist approach to e-road riding, opting for a lighter weight total system with the small but powerful motor in the rear hub and a small battery in the downtube that together offer a more stealthy e-bike powertrain.

Orbea calls it a “more bike” approach, with still “enough power and range”. It’s meant to offer just enough motorized e-bike assist to get you up the big climbs a bit faster, while still feeling like you are pedaling a bike, not riding a motorized bike.

What new in the MY21 Gain?

The biggest update to the new Gain since its original debut is the availability of a OMR carbon frameset, now with more sleek integration. Orbea’s next-to-top carbon monocoque construction sheds weight and smooths the ride over the original alloy frameset.

The motor is effectively the same, but the upgraded Ebikemotion X35 Plus is a bit more powerful and features improved torque sensors for smoother, more natural power output paired to your pedal input force. There’s also now the optional range extender bottle battery to add an extra 208Wh of power to the 248Wh inside the downtube (much like the Scott we saw recently.) The new e-bikes also have a new computer display that gives more info on battery status & output levels than the simple colored LED one-button control on the toptube.

The new carbon bikes feature a 1.5″ tapered headtube to fit FSA’s ICR fully internal cable routing through the stem, plus flat mount disc brakes, a 12mm front thru-axle, BB386EVO bottom bracket & round 27.2mm seatpost with an integrated wedge-style seatpost clamp. Because of the bolt-on interface with the ebikemotion X35 Plus hub motor, the Gains stick with a conventional 135x9mm rear axle.

The Gain Carbon also now includes an integrated German STVZO-approved rear taillight built-into the seatpost clamp, plus a neatly-integrated stem-mounted headlight with up to 60 lumen output. Both are designed for daytime running off the main battery to improve your visibility whenever you ride, then boosting headlight output for riding in lower light conditions.

Updated all-road geometry & almost-gravel tire clearance

The Orbea Gain Carbon has clearance for 40mm tires both front & rear, which goes a long way towards its versatility from road to light gravel riding. The updated e-bike also has tweaked geometry for “a more relaxed, intuitive cornering feel with a lower bottom bracket and shorter chainstays.”

Has anyone solved the issue of the parasitic/magnetic drag that occurs with hub motors after the bike has surpassed assist speed?

No, and it’s prevalent in both geared, and direct drive hub motors.
