Is This the Right Tricycle for You?
The Addmotor GRANDTAN X combines front and rear suspension with wide tyres, a step-through frame and electric pedal assistance. Its padded saddle and backrest suit riders looking for a comfortable upright position for everyday outings and recreational rides.
A strong choice for:
- Riders looking for a supportive seat and accessible frame
- Everyday trips with electric pedal assistance
- Riders seeking front and rear suspension, with room to store a full-size tricycle
Compare another model if:
- You need a compact folding trike for transport
- Your access route is too narrow for an 821 mm-wide trike
- Your reach or inside-leg measurement does not suit its dimensions

Why Choose the Addmotor GRANDTAN X?
Comfortable riding position
An adjustable padded saddle and backrest help you find a comfortable position. A wooden footboard provides a place to rest your feet when stationary.
Responsive assistance
A torque sensor works with seven assistance levels, while Shimano seven-speed gearing lets you adjust your pedalling effort.
Front and rear suspension
An 80 mm-travel front fork and rear spring shock absorbers help cushion bumps. Four-inch tyres add a broad contact patch for everyday routes and suitable light trails.
Rear differential
The rear wheels can rotate at different speeds through a turn. Slow down before corners and allow room for both rear wheels.
Lighting and braking
Three disc brakes, parking-brake controls, a headlight and rear lighting provide useful everyday equipment.
Battery capacity
The listed 48 V, 20 Ah battery provides 960 Wh of nominal energy capacity. Actual distance depends on your route and riding conditions.
Safety, Visibility and Ownership Support
Three wheels support the trike at a standstill, but a tricycle can still tip when cornering or travelling across a slope. Practise steering and braking in a quiet, open area before venturing onto busier routes.
Keep loads secure, maintain tyre pressures and use the charger specified for the supplied battery. Ask Trike Bike about servicing, parts and the electrical configuration of the model you are ordering.
Comfort, Rider Fit and Key Measurements
The manufacturer suggests a rider height of 157–193 cm. Check inside-leg reach, flexibility and control position as well as height. The published width is 821 mm and saddle adjustment is 826–991 mm.
Measure gates, storage areas and transport space before ordering. Ask us to confirm any critical clearance on the supplied trike.

Frequently Asked Questions
How do I check whether it will fit me?
Start with the sizing table, then speak with us about your inside-leg measurement, reach and mobility. A test ride can help establish comfort and control.
How does this differ from the GRANDTAN M-340?
The GRANDTAN X adds rear suspension alongside its front suspension. It has its own dimensions and weight, so use the X specifications when planning storage or transport.
Is the rear storage bag included?
No. The manufacturer states that the storage bag is not included. Ask us about available cargo accessories.
How far will one charge take me?
Distance changes with terrain, load and assistance. Tell us about your planned rides so we can discuss a realistic expectation.
