The Crow Gravital eGravel bikes are now on general sale. The bikes, first launched via an Indiegogo campaign, come in three styles: Gravital UL, Gravital SL and Gravital Risbar SL. Multiple models fall under each class, with six available bikes in the range.
The bikes are designed for rides across single-track or mountain bike trails. Each pedelec is equipped with a Fazua Ride 50 system, providing 250 W power, 55 Nm of torque and a 252 Wh battery. The motor can assist you at speeds up to 32 kph (~20 mph), depending on the rules in your country.
You can choose from four-speed modes, which you can control in the Fazua smartphone app. The Fazua Ride 50 can assist you for up to 80 km (~50 miles), though this will differ based on the conditions such as weather and terrain. The battery will recharge in around four hours, or to 80% in a little over two hours. You can also opt to remove the battery pack and ride without assistance.
The Risbar SL and SL models have an aluminum-carbon frame, while the more expensive UL series has a pure carbon frame. The lightest e-bike in the series, the UL 1 Ltd, weighs just 13 kg (~29 lbs). You can now buy the Crow Gravital e-bike starting from US$3,968.
