Ridley presents E-ASTR: Electric gravel bike with TQ drive

At the centre of the E-ASTR is the new TQ HPR40 drive. According to the manufacturer, the motor weighs just 1.2 kilograms and the associated battery 1.42 kilograms. The system is said to deliver a torque of 40 Newton metres and an output of 200 watts. Ridley emphasises the natural riding experience: the drive only provides support when needed, especially on technical or slow sections.

The battery has a capacity of 290 watt hours. For longer tours, Ridley offers an optional range extender with 160 watt hours. At first glance, the bike is barely recognisable as an e-bike: the motor is hidden behind the chainrings, the battery in the down tube. Instead of a display in the top tube, LEDs in the handlebar end indicate the selected support mode.

Geometry and equipment as on the ASTR RS

The E-ASTR fully adopts the geometry of the non-electric ASTR RS. The steering angle is 71.5 degrees, the seat tube angle 74 degrees. The bottom bracket drop is 75 millimetres and the chainstays measure 425 millimetres. Ridley hopes that this geometry will result in direct handling, good power transmission and playful riding behaviour. Another feature that Ridley has adopted from the ASTR RS is the generous tyre clearance of 52 millimetres.

Second E-Gravel model from Ridley

With the E-ASTR, Ridley presents its second e-bike after the all-road model E-GRIFN. The manufacturer sees great potential for electric assistance, particularly in the gravel sector. In contrast to heavy e-mountain bikes, the E-ASTR favours light, natural support. Ridley has announced that further models will be available as e-bikes in the future. The E-ASTR will be available from €7199 - fully equipped with SRAM Apex XPLR AXS 1x12. If you decide to upgrade to SRAM Rival XPLR, the entry-level price is 8199 euros. With Shimano's GRX800 DI2 2x gravel component group, the bike costs 8899 euros.
