Kickbike America Race Max 28 Adult Body-Powered Kick Scooter

This scooter is a good, solid platform that needs better components. 1.) Wheels and tires are serviceable, but of low-end quality and a bit too heavy to really take full advantage of the lowered rolling resistance of the 700c wheel. I would suggest Cane Creek rims as a mid-priced and much lighter solution along with Continental 4-Season tires for reliable puncture resistance, better rolling efficiency and road feel. 2.) Presta valves rather than schraeder. Most people who own 700c stuff utilize the presta, so changing out with existing tube stock would be a no-brainer. 3.) Presta pump that works. There is a greater availability of quality, durable, affordable frame pumps out there in presta than in schraeder style valve. The schraeder pump that comes with the bike is cheap plastic, and I could never get it to work. 4.) Bar grips just don't absorb vibration well enough, leaving hands numb within 5 miles. Fiz-ik padded bar tape would be a handsome, low-cost fix. I have the wheels to make the upgrade there by swapping with the road bikes, but plan to install a carbon bar and 32.8 mm stem to further lighten and improve vibration damping in future. I like the bike. Tracks straight and true. Have hit 35 mph on a short downhill smooth as silk. It's huge! Getting through your screen door before it closes on you is a challenge, but reasonably light given the geometry and frame tube wall thickness necessary in this application. I'm 210 pounds and rebound and frame flex is barely noticeable. Good overall value. Perhaps call this bike the Value Max 28 and save the Race Max 28 moniker for a future upgraded version that should come in about 1.7 pounds lighter with the modifications I have suggested above.
