Safety Notes: Manual (mechanical) shifting must be done while pedaling; avoid forcing electronic shifts at a standstill. Keep mountain tire pressure at 35–45 PSI. After off-road rides, rinse mud from fork tubes and brake pads. Always wear a certified helmet and follow local laws.
NOTED: Manual shifting requires shifting while pedaling; electronic shifting must not be forced while stopped. 25 MPH is only permitted on professional race tracks; on public roads, the speed must be limited to below 20 MPH via the instrument panel. Maintain mountain tire pressure between 35-45 PSI (below 30 PSI increases the risk of tire bursts, above 50 PSI causes a significant drop in traction); After each off-road ride, rinse the undercarriage of mud and sand, focusing on cleaning the front fork tubes and brake pads.
FAQ
Q1: Can the soft tail frame carry heavy loads? Can a rear seat be added?
→ A: This frame is designed purely for mountain biking and does not have a rear seat interface! The maximum load capacity is 150 kg (including equipment).
Q2: How do electronic and mechanical shifting work together?
→ A: Mechanical shifting controls subtle slopes (recommended gears 1-4), while electronic shifting is used for sudden steep slopes (gear 5 provides a 70% instant torque boost). Do not shift gears simultaneously!
Q3: Does terrain affect range?
→ A: Tested data:
– Pure electric mode: 25 miles on flat terrain → approximately 12-15 miles on mountainous terrain
– Assist mode: With electronic shifting engaged for climbing, range can still reach 25 miles+
Q4: Does the suspension fork require regular maintenance?
→ A: Special lubricant must be injected every 50 hours of riding or 500 miles.

For a 400W-rated bike, the GT900 feels surprisingly punchy. It accelerates well from stops and maintains a good cruising speed on flat roads. The range has been close to what’s advertised for me.
Samantha Scott –
Solid build and very smooth ride.
Christopher Thompson –
The geometry on this bike is comfortable for longer rides. The seat and handlebar position feel natural, and the motor makes headwinds and small climbs much easier to deal with.
