Overview
A 20 inch tandem style tricycle with a rear passenger seat, rated to 150 kg (about 330 lbs) for rider plus a second passenger. Built for adults and seniors who want to go out together at a relaxed pace.
The rear seat board lifts to reveal a hidden basket underneath, and there is a separate front basket too, so storage comes from two directions. Front and rear brakes are linked through a single handlebar lever setup, which matters when carrying two riders and needing to stop reliably.
- 20 inch wheels with high carbon steel frame
- Rear seat lifts to reveal hidden basket
- Front basket for extra storage
- Dual brake lever linked braking
Who it's for
Pairs, such as an older adult riding with a companion or grandchild, who want a stable low speed trike built for two. Not the choice for someone riding solo who just wants cargo space.
Strengths and trade-offs
Drawn from this product's published specifications.
- Carries two riders on one trike
- Hidden basket under the rear seat
- Height adjustable handlebar and saddle
- Linked front and rear braking
- Requires self-assembly after disassembled shipping
- 150 kg limit covers both riders plus cargo
- Review history not yet available
Performance notes
The 20 inch wheels and triangle steel frame keep the load stable at walking pace, and the linked front and rear brakes give more control when a second rider adds weight. Height adjustable handlebar and saddle let riders of different sizes set up their own fit.
