Mobo Cruiser Triton Pro Tricycle Unisex

I purchased 2 of these bikes for my kids ages 9 and 11. I am a long distance runner and wanted to include my children in on my daily runs. The bikes looked comfortable enough for the kids to chase me around in. I didn't think twice about the price tag, I'm a believer of "you get what you pay for" therefore, I expected a sturdy cycle that would perform above and beyond. This is a single gear bicycle without a chain - what does that mean for the child? Your child will pedal as hard and as fast as he/she possibly can and the bicycle will not travel any faster. The front wheel is much to small to generate the required amount of friction to propel your child. Essentially, my children tired in less than half the time they would've in their traditional bikes. Not only were they fatigued, they were very frustrated. Aside from the lack of speed, the front wheel will not remain on the ground if they are on any kind of climb. We were riding on a smooth sidewalk with a gradual climb, nothing big - but the children could not keep the wheel on the ground long enough to gain any traction. All in all, it was a poor purchase. I would've rather purchased the cheapo Walmart bikes, saved myself about $500 and my children would've been incredibly happy. I just wish I'd kept the boxes so that I could've returned them. The assembly was as to be expected, lots of parts but the instructions were pleasantly clear.
