Orbea Gain M30 GRX 600 Disc Electric Gravel Bike 2021
Set off on your next adventure without being restricted to the road with the Orbea Gain M30 GRX 600 Disc Electric 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.
