Electric Mountain Bike ECONO Gams MTB 29 C7 (2026 Series)
The pinnacle of Gams series performance: Uncompromising MTB power with top-tier Shimano XT equipment and 110 Nm of torque.

Who is the ECONO Gams MTB 29 C7 best for?
The C7 model represents the absolute top of the Gams family range. This is a bike for riders who are not just looking for a means of transport, but a sports machine capable of conquering the steepest climbs and technically demanding terrains. It combines the robustness of a true mountain bike (MTB) with the comfort you expect on longer expeditions. If you want maximum motor responsiveness, superior shifting precision, and stability on 29-inch wheels, the C7 is your first choice.

Model Comparison: Gams C7 vs Gams C6
Perhaps you're wondering why choose the C7 over the C6? The difference lies in the details that mean a lot on the trail:
- Shifting System: While the C6 offers standard reliability, the C7 uses the elite Shimano Deore XT 11-speed system, which is lighter, faster, and more resistant to e-motor loads.
- Cassette Range: The C7 is equipped with an 11-50T cassette, giving you a significantly easier gear for extreme climbs compared to lower models.
- Responsiveness: The optimization of the Bafang M510 motor in the C7 model is geared towards maximizing torque for sporty riding, ensuring more aggressive acceleration out of corners.

Bafang M510: Brutal 110 Nm Torque
At the heart of the bike beats the latest generation Bafang M510 motor. Although it operates with a nominal power of 250 W, making it a road-legal bike (speed limit up to 25 km/h), its torque is what truly impresses. With 110 Nm of thrust, you'll conquer climbs where other riders dismount.
The motor is designed for high efficiency and a natural pedaling feel. An integrated torque sensor measures your pedal pressure force thousands of times per second and adjusts assistance accordingly, preventing "jerking" and ensuring a smooth ride.

Smart Energy and Fast Charging
The ECONO Gams C7 uses an advanced Comtron ELK smart battery system, fully integrated into the downtube of the frame, yet easily removable with a key. Three capacities are available: 520 Wh (15 Ah), 700 Wh (20 Ah), and an extreme 800 Wh (23 Ah).
The smart BMS system in the battery ensures a long cell lifespan and safe operation in all conditions. Standard 2A charger included with every battery capacity. A 4A fast charger can be purchased separately.

Shimano Deore XT: The Standard in Professional Mountain Biking
Power transfer is handled by the 11-speed Shimano Deore XT RD-M8130 SGS derailleur. This series is known for its Linkglide technology, specifically developed for high-torque e-bikes. Shifting is smooth, quiet, and extremely precise, even when the Bafang motor is operating at full power. The Shimano CUES LG700 cassette with a wide 11-50T range ensures you'll always find the right rhythm, regardless of the terrain's incline.

4-Piston Stopping Power and Air Suspension
Safety at high speeds and on steep descents is provided by 4-piston hydraulic disc brakes Shimano DEORE (BR-MT420). A higher number of pistons means better modulation and significantly greater braking force compared to standard 2-piston braking systems. In combination with 180 mm rotors front and rear, the bike stops instantly when needed.
Comfort and grip are ensured by SR Suntour XCM32 AIR-BOOST air forks with 100 mm of travel, which can be precisely adjusted to your body weight via air pressure.

Smart Bafang DP C080 Color Display
On the handlebars is a compact and robust Bafang DP C080 color LCD display. It's positioned to the side, protecting it from damage in potential falls, while allowing operation without removing your hand from the grip. It offers 5 levels of assistance (ECO, TOUR, SPORT, SPORT+, BOOST) and level 0 for riding without motor assistance (without motor resistance). The display supports Bluetooth connectivity and app usage to monitor all riding parameters.

Stability and Grip: 29" Wheels and Schwalbe Tires
The Gams C7 rides on 29-inch ROVER XL (622x30C) rims, which allow easier passage over obstacles and better inertia. The Schwalbe Johnny Watts 29x2.35 tires are ideal for SUV/MTB use – their tread offers low rolling resistance on asphalt and excellent side grip on forest trails. DD (Double Defense) and RaceGuard technology ensure a high level of puncture protection.
