20 in Boys Avigo Air Flex for sale. It has dual / full suspension (fork and frame) and caliper brakes for both front and back wheels. It is a 7-speed bicycle with Shimano rear derailleur. The gear shifter is on the correct handle and by twisting it you can change gears.
Bike is in good condition but in use. It all operates well. The only thing I noticed was that the pedal sides were damaged. The pedals have this plastic loop at the end instead of being entirely robust. The loop-out is cracked on the left side and lacking on the right (see pictures). So you might want to substitute them with a different set of pedals. Otherwise, my son used the bicycle like that just fine, it's more of a cosmetic thing, IMO, just slightly decreasing the surface area on the one hand that no longer has the loop.
It's fairly nice, other than that. There are no functional problems. Brakes, gears / shifters, and all work well with suspension. Tires still in excellent form, much left wear. Normal wear / use signs but actually fairly great, particularly given that a child used it. He rode it predominantly on paved streets around the neighborhood, no tricks or off-roads or anything like that.
