I purchased the Alpha Three for my 5-1/2 year old son after researching pretty much all options in the 20” kid bike category. I settled on the Alpha Three because it had the best combination of all the attributes important to me – a good gear ratio, lightweight, trigger shifting, and accommodating standover height, all for a reasonable price tag. I really like the gear ratio Prevelo chose with the 32T up front and the 11-34T in the rear. A wide gear ratio including low gearing was important to me considering the hilly terrain we live in. Needless to say, my son (not the strongest kid) can power up hills much steeper than I thought possible for him. All of the comparable bikes, other than the pure mountain bikes, have gear ratio ranges that are very narrow and are more for flat, less hilly terrain. In my mind, it is more important for a little kid to easily get up a hill than attain top speed on the flats. My only recommendation would be to maybe even go a bit further to something like a 30T in the front and 11-36T in the back for even more range and good climbing ability. The trigger shifter was also another must for me. The main choice in shifters for kid bikes is either the trigger or twist grip. The reason I like the trigger is because that is what most big kid/adult hybrid, fitness, and mountain bikes use, not grip shifters, so why not learn to use what just about everyone else uses? My son is on the smaller side with small hands and he had zero issue with using the trigger shifter on the Alpha three. I think the combination large gear ratio and trigger shifter offering on the Alpha Three is a huge differentiator because no other comparable bikes come close. Really great bike that a kid can confidently ride on the pavement and the dirt/gravel at a great value for the components you get. I agree with the other reviewers in that the interactions I had with the Prevelo team were great – very prompt, helpful, amazing customer service, and the assembly of the bike was a breeze. Keep up the good work!
