Key Performance Features of the Addmotor Grandtan
Trikes require specific mechanical engineering to handle corners and carry cargo safely. The Grandtan incorporates dedicated stabilization components designed to prevent tipping and ease mounting.
- Mechanical Rear Axle Differential: Allows the two rear wheels to rotate independently during turns, eliminating tire scrubbing and providing smooth, predictable handling around tight corners.
- 750W Brushless Powertrain: Provides dependable hill-climbing leverage and smooth starts under load, delivering steady acceleration up to 20 MPH on throttle or pedal assist.
- 48V 20Ah (960Wh) Battery: High-capacity pack using certified lithium-ion cells, delivering up to 85–90 miles per charge on low pedal assist and key-removable for indoor charging.
- 3-Wheel Fat Tire Architecture: A 24" x 4.0" front tire rolls smoothly over curbs and bumps, while dual 20" x 4.0" rear tires keep the cargo center of gravity low and stable across uneven terrain.
- Ultra-Low Step-Thru Frame & Wooden Footrest: Features an accessible low-clearance top tube for effortless mounting, complemented by an integrated wooden footboard for relaxed riding ergonomics.
- Triple Disc Brakes with Parking Lock: Hand levers feature integrated mechanical push-button parking locks to keep the trike stationary on inclines during loading and parking.
- Heavy-Duty Rear Cargo Basket: Rigid rear utility basket carries groceries, tools, or gear bags, contributing to an overall vehicle payload capacity of 450 lbs.
Who the Addmotor Grandtan Is Built For
The Grandtan is engineered for adult riders, seniors, and utility shoppers who prioritize zero-effort balance, upright comfort, and substantial cargo utility. It allows riders who no longer feel comfortable on two wheels to continue exploring neighborhoods, greenway trails, and local community paths with confidence.
Frequently Asked Questions
How does the rear differential improve steering?
On basic trikes with a solid axle, both wheels turn at the exact same speed, causing the inner wheel to skid during turns. The Grandtan’s differential allows the outside wheel to turn faster than the inside wheel, keeping the trike planted and stable throughout curves.
Does the trike stay upright when stopped?
Yes. The three-wheel stance is self-supporting, meaning you do not have to put your feet on the ground at stop signs or traffic signals.
Can the battery be recharged on or off the trike?
Yes. The battery can be plugged directly into an outlet while mounted beneath the saddle, or unlocked with the included key to charge inside your residence.
