Don't buy this, mine completely fell apart in less than 90 days. You'd be better off with a tarp.

Yes. I have 2 boys. We put 2 Mongoose Bikes and an adult bike and they fit with no problem.

Hey Christine. How tall? I'd say if he's over 5'0 then you'd want something bigger to allow some growing room. Otherwise this will be a good bike.

go with the 24" unless you are still growing. there is some seat adjustment height in all bikes but this type of bike is an entry level one size fits most model. my suggestion would be to visit a bike shop and see if a 24 or 26 feels better to you. FYI this was purchased for a granddaughter and see is about 5'1" and it fits her fine. good luck and happy trails. the bassetfarm

12 inch is perfect for my 3 year old grand sons, a four year old may need bigger. Go to Target or Walmart and just look at the 12 inch and 16 inch bike and that might help you decide before you order from Amazon.

Go with the 16" wheels. My son is 43" inches now and we just moved him up to 18" wheels. He learned how to ride to ride a two wheeler with the 14" wheels last year, but he was 40" at the time and now has outgrown that bike.

Medium should do it. I have the large on a v star motrocycle 250 and it is more than I need.

I do not know. Somewhere I found a sizing chart. It might have been on another site. I do remember putting in my model of bike into the sites system, and the system came back and told me it was a compatible fit. I think it was Motercycle Superstore. I ordered the same size from Amazon. Sorry I can not be of more help.Paul

This bike is for 8 years and up. Got big wheels. I don't think you can mount training wheels on it. You can look for training wheels that fit 20" bike wheels. I hope it will help.

I'm not completely familiar with thier bikes, but typically the 50cm is the frame size fit for 5'2"-5'9" males and there is the 55cm fit for taller men. But as for the 20cm, I'm guessing that's a typo?The important difference between frame size is the hight of the bike - from your seat to the floor. And the length of the bike - from the seat to the handlebars. Hope this helps.

If he doesnt already ride a pedal bike I would recommend the 12" you will inevitably have to get the 16" as well but use the 12" to boost confidence. I have a 4 and 6 year old and my older boy is just now getting comfortable with the 16" he kept trying to steal back the little bike

Either the 24" or the 26" should suffice. The size is more a reference to the tire size than it is the actual physical stautre of the Tricycle. The frame is the same for both the 24" and the 26". There is ample adjustment on the seat to accommodate you needs.

With the basket I'd certainly recommend the large but if the bike is small, medium might work.

They have a size chart on the website that could help you more. Go to criticalcycles.com

The tire I got was 20 x 1.75. (That is 20" diameter & 1.75 inches wide)It was an exact replacement for the one I needed. Most 20" bikes will use tires from 1.75" to 2.50" width. Hand brakes may need adjusting for width of tire.

the tire size will be the size of the rim if its a 20" rim you need a 20" tire
