Uh, be careful riding on the sidewalk with this. I hit a bump, got thrown off my scooter and broke my wrist. The suspension on the front isn't a foolproof safety net for rough terrain.
autoteleologyHi, autoteleology, sorry to hear that and wish you a speedy recovery.
You are right that everyone should pay more attention on the roads and obstacles, especially for a vehicle like this. The smaller wheel is inevitable more sensitive to bumps on the road and we would like everyone to understand the tradeoff as well. Thanks.
