Overview
This Sun Flat Top unicycle uses a stiffened high-tensile steel frame meant to resist flex during freestyle moves, paired with sealed bearing hubs and a scuff-guarded saddle. Sun offers the Flat Top design in both 20 inch and 24 inch wheel sizes, so it is worth confirming which wheel size your order includes before buying.
A recurring complaint is that units have arrived without assembly hardware or with shipping damage, issues buyers had to resolve through the seller rather than problems with the unicycle's design itself.
- High-tensile steel Flat Top frame
- Sealed bearing hub for smooth rolling
- Scuff-guarded classic saddle
- Available in 20 inch and 24 inch wheel sizes
Who it's for
Suits beginners and casual riders who want a durable first unicycle that can absorb falls without much cosmetic damage. Riders around 5 foot 11 and taller report the frame fitting them, though shortening the seat post may help smaller riders.
Pros and cons
- Sturdy steel frame that holds up to repeated falls
- Scuff guards protect the seat during learning
- Praised as good value for the build quality
- Some units arrive missing assembly hardware
- Seat post clamp can be fiddly to adjust or lock down
- Shipping damage reported on at least one order
Performance notes
The flat top steel frame is designed to add stiffness at the crown, which helps it resist flexing during tricks and gives freestylers a place to plant a foot.
