My son had been on a balance bike for about 7 months and I had the feeling that he was ready to try out his first pedal bike. I am the type to get into the details and do too much research so I spent a good bit of time (okay, a ton) figuring out the different options out there. There a few really good sites like twowheelingtots.com and rascalrides.com that have a lot of great reviews on their sites, but they also teach you what to look for in your first balance bike and your first or second pedal bikes. It seemed like getting the right bike, especially with the first pedal bike would make a huge difference on how quickly and easily my son would learn to pedal. He is 3 yrs, 9 mo, 39.5" tall, with a 16" inseam, and 35 lbs. So I was looking for a bike that was as light as possible, with 14" wheels, a minimum seat height of no more than 17" (preferably 16"), and kid-friendly geometry. But my son is also really comfortable on his balance bike, riding beginner mtn bike trails, a pump track, has done a couple strider class bmx races, and can balance indefinitely, so I didn't want it to be so upright that he wouldn't be able to grow into it a little and progress to more aggressive riding. I also wanted to ensure I was able to put a freewheel on the rear hub. I had a lot of trouble finding a bike that checked all the boxes. One had 12" wheels with too aggressive of a geometry, one did not offer a freewheel kit (coaster brake only), and one was too upright with the minimum seat height a little too tall. So I commented on one of the aforementioned sites asking for advice, and I got a response to look at the Prevelo Alpha One which was new and just hadn't been reviewed or added to the site yet. I'm willing to bet now after getting the bike and 4 or 5 rides that Prevelo will have all their bikes near or at the top of the list on every bike review site out there before too long. For what it's worth, I spent almost as much time looking into his first balance bike. While I got one of the better balance bikes I could get at the time (last October), I wish the Prevelo Alpha Zero had been out when I bought it, as it solves every little thing I don't like about the one we got. It's definitely the way I'd go if we were buying again. As for the Alpha One, it meets all our needs. 14" wheels, about 13 lbs, minimum seat height is 15.6" (best I've seen for this size bike), the cranks and stance appear to fit him well. I don't have any reservations about taking it to the mtn bike trails when he's ready. Freewheel kit available. The quality seems really good, brakes are good quality tektro brand, internally routed rear cable (only bike I've seen this on), welds look as good as my $1200 road bike. And it's just a really good looking bike in my opinion. My son loves it. I unpacked it during his nap, put on the handlebars, and swapped out the rear wheel with the freewheel kit. I also dropped the seatpost down pretty low and left the pedals off at first just to let him ride it around the house for a little bit to get use to it. After dinner we took off outside. Again, I let him ride it for a little while without the pedals. I then put just one pedal on to practice a "one pedal scoot" which is the technique he uses to get moving before he move his second foot to the pedal. We then raised the seat a little and put on the second pedal. From when we put the second pedal on, it was only 10 minutes before he was riding by himself. I was so impressed and so, so proud. And the joy on my son's face and the laughter from his voice was priceless. On his second day, he's even making his way up the hills in the neighborhood. I know his balance bike experience helped a ton, but I also think his comfort on the bike has helped him pick it up very quick. I am also extremely impressed with the people at Prevelo. Their website is phenomenal with all the info you need to get going. Great pictorial instructions for bike assembly, freewheel kit installation, bike fit, tire pressure, etc. And the people at Prevelo have been great. I emailed multiple questions over multiple emails, and Jacob Rheuban replied promptly each time with thoughtful responses and honestly seemed to appreciate that I was asking questions. I can tell he is also genuinely interested in my son having a successful first pedal bike experience. And he ultimately helped me decide on the right bike since my son potentially could have gone either way between the Alpha One and Alpha Two. Once ordered, the communication was great with updates along the way about when it would ship and when it would arrive. They even added a personal touch to the bike for my son. I also asked a question about the freewheel kit installation before my bike got to me. They had literally answered my question and updated the instructions on their website within an hour. One of the best shopping experiences I've had ever. I will be a Prevelo customer for a long time.
