Orbea Gain D30 GRX 600 Disc Electric Gravel Bike 2021

For long mixed-surface adventures that you simply want to enjoy to the full, treat yourself to an Orbea Gain D30 GRX 600 Disc Electric Gravel Bike. The powerful motor is housed in the rear wheel and is designed to enhance your ride rather than dominate it adding extra power up to a maximum speed of 15.5 mph / 25 km/h. So, you can call upon its 250 watts of assistance when you want it, and ride freely without assistance when you don't.

The 248Whr battery is housed in the down tube, and the neat Mahle Ebikemotion iWoc ONE remote interface will let you know how much power you have left among other metrics. Also in the head unit, you'll find a 60 lumen integrated front light, with a rear light housed in the seatpost too.

A Shimano GRX groupset is specified here with a 1 x 11-speed setup that's perfect for choppy trails and long canal tow-paths, with the wide-ranging 11-40t cassette combining with the 40t chainring for loads of gearing options. The grippy Vittoria Terreno Dry Gravel G2.0 tyres come in a size 38c, so you'll have comfort and traction wherever you ride.
