Cannondale Topstone Neo SL 1 Disc Electric Gravel Bike 2023

Making use of the lightweight Mahle ebikemotion X35+ motor assistance unit and blending it with a rugged, efficient and comfortable frameset, the Cannondale Topstone Neo SL 1 Disc Electric Gravel Bike is ready and set to explore long into the wilderness across the most challenging terrain.

The Mahle ebikemotion X35+ rear hub motor is one of the lightest assistance units available that can also boast exceptional reliability and power. Producing up to 250 watts of assistance, this motor helps the rider up sharp hills, across enduring tracks and when battling against strong headwinds. Partnering the motor, the X35 battery lasts for up to 47 miles, is recharged from flat in just 3.5 hours and is concealed within the frame’s downtube to afford a super-clean silhouette. The system is controlled by the iWoc ONE unit that is neatly integrated into the top tube. This unit is intuitive in use, adjusts between three motor assistance levels and provides visual feedback on the amount of battery charge remaining.

This bike has an electric assisted speed limit of 15.5 mph / 25 km/h.

The aluminium frame and carbon fork combine to give a reactive, lively and smooth ride and donate plenty of mounting points for bottles, racks and luggage. The frameset is realised with an endurance inspired fit that balances comfort and speed and grants enough clearance for plush and grippy 42mm wide tyres.

Strong wheels handle rough terrain with aplomb, and Shimano 11-speed gears shift crisply across a wide range of ratios. Hydraulic disc brakes are added to the build, with these providing excellent stopping power in all weather conditions.
