    Good lightweight bike with a better braking system

    I guess annoyed they are not available anywhere but Guardian and the bikes have limited color choices. But sizing info, array of bike choices (especially having small and large 20in) available is unique, ordering is easy, there shipping is fast, packing protects the bike, assembly is easy, and child likes it. They seem well built and the brake system is superior.

    Smart bikes!!

    I got a 20” large for 7 yr old daughter and a 24” for my 9 yr old son. The shipping was crazy fast and the bikes arrived in perfect condition and almost ready to ride. I have been hesitant to order bikes straight to doorstep before because setup can get tricky, but these had a super easy set up: pedals, handlebar, front tire, inflate the tires. Done. All necessary tools were included, except you will want a phillips screwdriver for the front deflector and scissors for a zip tie. The brakes stop the bike really well. The kids seemed balanced and comfortable operating them, and it was their first go at hand brakes. It is nice to know that they can’t flip themselves over the front tire with these brakes! (I think they definitely would have the first time they super-grabbed that lever if they had picked the wrong one!) The gear shifter is nice and they are able to operate it with their grip strength. Having the different gear options really improved their ability to ride. They can go over grass and navigate hills a lot better which is game changer for the rural area we live in. The 24” even has an extra large 1st gear which was an unexpected fancy feature and my son seems to notice that he can really do more with that 1st gear than he could before. The build of the frame on these bikes is really clever and definitely helps kids fit better and ride easier, giving them access to larger wheel sizes that on other frames would be too big. My only wish is that I had gotten them bikes like this right from the start! I will probably be buying a 14” for my youngest as soon as he is ready.
