Dark, cold and usually a headwind: in winter, riding to work takes some willpower. This is exactly where the GT Grade Power Series shines. It is a proper gravel bike with a quiet hub motor that helps you on climbs and into the wind, and rides like a normal bike without assistance. All three models are in stock.
Light, quiet, discreet
At its heart is the MAHLE X35+ 250 W rear hub motor. The 245 Wh battery sits invisibly in the down tube, and you choose the assistance level with a button on the frame. At 14.5 to 14.9 kg the Grade is a lightweight among e-bikes and easy to carry down to the basement. Depending on the assistance level, one charge lasts 60 to 100 km, so with a 15 km commute that is two to three days there and back. At first glance hardly anyone notices it is an e-bike, and without the motor it rides like a normal gravel bike.
Why winter?
- Arrive without sweating: the motor takes care of climbs and headwind, so you arrive relaxed even in a thick jacket.
- Grip and comfort: the frame's floating stays absorb bumps, and the 42 mm WTB tyres give you grip on wet leaves and gravel.
- Brakes for any weather: hydraulic disc brakes bite reliably in wet and cold conditions.
- Ready for mudguards and luggage: the carbon fork has mounts for mudguards, bottle cages and racks. For a tool-free option, the SKS Speedrocker gravel mudguard set attaches with straps and fits tyres up to 42 mm, exactly what the Grade runs.
- Little wear: the hub motor drives the rear wheel directly, so chain and cassette take no extra load.
Which Grade suits you?
For the daily commute and city rides, the Grade Current with its flat bar is the first choice. If you ride more sportily and also cover longer distances on tarmac, go for the Grade Bolt with drop bar and Shimano GRX 2x10. The Grade AMP is the top model for long gravel days, with GRX 1x11 and tubeless tyres.
GT Grade Current
Gun
Flat bar and upright riding position, microSHIFT Advent X 1x10. The commuter of the three.
GT Grade Bolt
Deep Teal
Drop bar and Shimano GRX 2x10 with close gear steps, for sporty commuting and fast rides.
GT Grade AMP
Satin Bronze
The top model with Shimano GRX 1x11 (11–42) and WTB Resolute tubeless tyres for lots of gravel.
Also available as a company bike
You can lease all three Grade models through your employer or as a self-employed rider in Germany, for example via JobRad, Business Bike, Bikeleasing, Deutsche Dienstrad, Kazenmaier, eurorad or Lease a Bike. Whether it pays off for you depends on your salary, your employer's contribution and the term. Best run the numbers with your leasing provider's calculator. How to request an offer is explained on our bike leasing page.
Three tips for the cold season
- Charge the battery warm: cold reduces range. Charge the battery at room temperature and plan a little less range on frosty days.
- Be seen: for dark mornings and evenings you need proper lights. Clip-on battery lights are quick to fit.
- Rinse off road salt: after riding on gritted roads, rinse the bike with water (no pressure washer) and oil the chain.
