I have an Alton with 451 wheels. Fun bike, super maneuverable. I have it set up kinda like a large BMX bike with slick tires. This is my choice bike for attempting daft tricks.
Like with any mini-velo, the small wheels let you accelerate very quickly and the reduced gyro effect make it very nimble.
It is a such fun and unintimidating bike that even my trouble and strife will have go on it.
Yeah I like it a lot.
