My son is a few months under 3, 38" and 29 lbs -- is he big enough to use this? He's desperate for his own exercise bike but I'm not sure

Hi Mariana, based on Redmon specs the recommended age is 3-6 years and the seat height is adjustable from 18.5" to 21.5" (floor to top of seat).Hope this helps you in deciding. Zilbex Customer Service

How tall does the bike seat raise to?

Seat height is 15.75" from floor to top of seat (max), Seat dimensions 7"W x 22.75"L (overall seat length)

Lol! fits up to 4.75lbs? that would be one very very small newborn baby size!!!

I used it in my 4-5 year old preschool classroom. The kids liked it but the only trouble I had with it was keeping the seat pole up. It kept sliding down. Maybe someone who knows anything about bikes could have easily fixed it but I couldn’t.
