Query: Unimax Pit Wheeler Trike

I liked the style of this trike as compared to the others, but I wasdissapointed in the quality. The bearings for the rear wheels are just plastic bushings. Also my four year old son broke the screw holding the pedal shaft to the wheel. I had to drill a hole completely through the shaft and install good bolt. I have friends who bought the John Deere Trike with the strait handle bar, and it was much better quality.
