5.0 out of 5 stars Extremely High Quality Bike (with a couple of minor exceptions), June 27, 2009

Very impressed with the quality; its immediately clear coming out of the box that this is not a cheaply made bike. Even the training wheels are made from solid rubber and metal. Only had two issues. First, there were no assembly instructions in the box (although not really much to assemble; i.e., front wheel, pedals, handle bars, training wheels and seat). There was an owners manual with the bike (how to ride, safety instructions, adjustments, etc.) but nothing specific to this actual bike or its assembly. And secondly, the seat covering was trimmed short on a small spot in the back so that a couple of staples were not making any contact with the internal hard frame in the seat -- albiet minor, I would still consider this a defect in workmanship and might call the company about sending me a replacement. All considered though, we are delighted with the bike and trust that it will easily be in use for many years to come. Very highly recommend!!!

4.0 out of 5 stars Perfect fit for my 3-year-old, July 9, 2010

This review is from: Diamondback Kids' Mini Viper BMX Bike (Sports)

I bought this bike for my 3-year-old son and hoped it would fit him and be something he could grow with. We've had one trip around the block and I can already tell it will fill that role very well. The parts appear very durable, the seat is comfortable, the training wheels are very sturdy, and the bike comes with a chain guard not shown in the photo.

I didn't subtract a star from this bike because it is heavy, and it is heavy. Nor was the subtraction due to the the ever-so-slight wobble in the sprocket that causes a minimally inconsistent feel as the cranks are turned a full rotation. I subtracted a star because there is excessive and unnecessary drag in the drive train and bearings and many of the bearings feel a little "catchy". In an attempt to remedy this, I removed the fork and thoroughly greased those bearings, which lead to substantial improvement in ease and smoothness of steering. I'd like to lubricate the drivetrain, but unfortunately, I can't seem to loosen the nut to access the bottom bracket without destroying the paint. I didn't bother with the wheel bearings yet and I likely won't. I'm not a bike mechanic and don't want to chance wrecking my son's gift the same day I gave it to him. Reducing drag for little riders who are trying to develop muscle and balance all at once would seem to me to be a significant priority; the fact that the manufacturer didn't pay as much attention to this issue as I would like was enough for me to feel mild disappointment with this one aspect.

That said, my son didn't seem to much notice the resistance as he pedaled this behemoth up a sizable hill on our way back home, nor was it enough to prevent him from starting the bike from full stop on almost all occasions as he practiced braking, and to be fair, I'm a little spoiled by my much more expensive bike. My son loves his new bike and so do I; despite my issue, I'd buy it again or recommend it to a friend in a heartbeat.

If you're like me and you don't feel like dropping $250 on a Specialized or Trek bike for your 4 year old, then the Diamondback Viper is the perfect solution. You might be thinking, "Heck, I might as well buy an $80 bike if I'm going to save money." Big mistake. My in-laws ordered one of the cheap-os for my kid's birthday. Total junk. Sent it back and upgraded to the Viper. It's very solidly built and has quality components. The training wheels are really durable. They're not the flimsy, rattly kind found on cheaper bikes. Yes, overall it's a little on the heavy side, but who cares. An extra pound isn't going to break your back lifting it out of the car.
