Orbea Gain D40 Tiagra Disc E-Road Bike 2021
Designed not to dominate the ride, but rather, to enhance it, the Orbea Gain D40 Tiagra Disc E-Road Bike has a powerful 250-watt motor that only engages when you want it to. When coasting along on the flat, you'll barely notice it's there but push the button on the top tube on a steep climb and enjoy the boost of power coming through the rear hub motor.
With the battery concealed neatly in the downtube and the motor within the rear hub, the Gain D40 looks less like an E-Bike and more like a traditional road bike. Those clean lines continue through the cockpit with the cables neatly concealed within the stem. And with integrated lights at the seatpost and out-front display interface, this is a very well finished bike with some real premium touches.
Shimano's Tiagra 4700 is seen as an excellent value 10-speed groupset, with plenty of trickle-down technology to make the shifting crisp and responsive. The addition of hydraulic disc brakes delivers a premium braking experience too, whatever the weather. Comfort is boosted through the 30mm wide Hutchinson Fusion 5 tyres, so you can enjoy long adventures, wherever the road may take you.
