2021 Orbea Gain D50

The 2021 Orbea Gain D50 doesn’t look like an electric pedal assist road/gravel bicycle. Hop on for a few miles and you'll notice it doesn't ride like one, either. Call Contender Bicycles at 801-364-0344 for availability.


Product Description

The smooth, but powerful, pedal assist electric motor on the 2021 Orbea Gain D50 is so light you’ll hardly notice it. The same goes for the seamless boosts of momentum you’ll receive as the engine senses your cadence and transfers power to your wheel.

The Orbea Gain D50 is not just a pedal assist bicycle. With its beautiful design and industry leading technology, the Gain will change the way you ride whether that be on the highway, on gravel, or the parkway bike path commuting to work.

Install a set of gravel tires and head into the backroads. Ride with a pair of narrower road tires and you’ll fit in perfectly with the club ride on the weekend.

Orbea has introduced the PAS Sensor to the Gain lineup. PAS is integrated into the rear wheel motor and cassette to monitor every pedal stroke - with 40 pulses per cycle - and determine when, how and how much to deliver power to your ride, resulting in fewer lags in power delivery when riding conditions change.

The EbikeMotion X35 Plus motor transmits reliable and balanced pedal assist to improve your rides without taking over and making them too easy. The torque simulation algorithm helps match power input with each pedal stroke to generate what Orbea calls Enough Energy Concept - not too much, not too little. There are three levels of pedal assist with a max speed of 20 miles per hour before the motor decides you’re fast enough to hold your own.

The Orbea Gain D50 features internally routed cables to keep the look of the bike crisp while also boosting aerodynamics. Integrated lights on the back of the seat clamp and built into the bike computer mount add yet another touch of class while also aiding air flow. The iWoc ONE interface and display allow convenient data monitoring and push-button control.

With only one external cable connection - under the chainstay connecting the battery tube and the real wheel motor, changing tires is simplified.

Built on a lightweight alloy frame with Shimano Claris components, the Orbea Gain D50 has a 2x8 speed drivetrain to embrace its road design heritage.
