Orbea Gain M30 GRX 600 Disc E-Gravel Bike 2021
Set off on your next adventure without being restricted to the road with the Orbea Gain M30 GRX 600 Disc E-Gravel Bike. Towpaths, fire roads and single track of any gradient are tamed by the powerful 250-watt motor while the lightweight carbon fibre frameset provides a comfortable and nimble ride.
With the motor mounted to the rear hub and the battery hidden in the downtube, this looks like a regular gravel bike at first glance. But when you need a little assistance, the powerful 250-watt Mahle Ebikemotion motor can be switched on at the push of a button. When disengaged, the motor doesn't hinder the drivetrain so you can ride unimpeded.
The dedicated gravel specification on this bike includes the superb Shimano GRX 600 groupset, offering a 1 x 11-speed gearing setup. With less maintenance thanks to the single chainring and all the ratios you need for any terrain, it's a fantastic option that also boasts powerful hydraulic disc brakes for superior stopping power. The bike comes fitted with Schwalbe G-ONE Bite clincher tyres, perfect for mixed terrain, so you can get out exploring from day one.
