My daughter, who is developmentally delayed, has owned the smaller version of this trike (the Mobo Mobito) for 7 years. She has just outgrown it and we've upgraded to the Mobo Shift. Pros: - Fun. My daughter has a blast on these trikes. She has definitely traveled over 500km on it in the 7 years she's had the Mobito, probably over 1000km. She has explored all the sidewalks and alleyways and bike paths around here, typically on 4-5km trips. She has splashed through every puddle she could find. Winter, spring, summer, fall, she loves to be out on her trike. - Visual design. Kids spontaneously say "Cool bike!" when we pass them on the sidewalk. It's a nice-looking trike. We had the yellow Mobito, which I think helped with that "wow!" factor. - Low maintenance. Other than replacing tires because of all the miles she put on it and occasionally tightening up bolts, it required little maintenance. - Grows with you. My daughter grew a lot over 7 years. Lengthening the trike was as simple as flipping the quick-release nut, pulling the pin, and sliding it back a notch. Financially, that made the trike a great purchase for us. Things I tuned/improved: - Push bar. I got some 1" x 4' square steel tubing from the hardware store and added a push bar. I used BMX pegs for handles. This required drilling a couple of holes in the frame, but it was well worth it. I used the push bar to help her turn, pull her out of mud puddles, and make sure she stopped at crosswalks. Mobo offers a push bar for their toddler trikes, but it would be nice to have it as a standard option for their bigger trikes, too. - Easier steering. My daughter has trouble with the full strength of the steering springs, so I removed one of the two springs to make it easier for her to steer. - Easier braking. My daughter's hands are on the small and weak side, so I tuned all the brake springs and screws to make it as easy as possible for her to brake. The front wheel wasn't trued up enough from the factory for such close-tolerance braking, so some spoke adjustment was required, too. Cons: - Downhill danger. Going fast down a hill is dangerous on this trike. My daughter tipped the trike over twice when doing a sharp turn after going fast down a hill. She always wears her bike helmet while riding, so luckily she got away with just a few scrapes both times. With two wheels in the back and one in the front, it's reminiscent of the infamously unstable Honda three wheeled ATVs. To be fair to Mobo, they do say that their trikes are unsuitable for hills. - Uphill pedaling. With most of the weight over the back wheels and little over the front wheel, the front wheel starts to slip on even small slopes. I guess with downhill riding being so dangerous you could count this as a safety feature, since if you can't go up a hill you can't ride back down. Having the seat just a bit further forward to help with uphill pedaling grip would be nice, though. - Steering tube design. The steering tubes point straight down, instead of pointing at the spot where the tire rubber meets the road. This means that both back wheels are constantly being pulled back toward 90 degrees, but in opposite directions. They dealt with this problem by adding a couple of springs to pull the steering straight, but it's a hack fix. If the back wheels are out of alignment, the steering starts oscillating wildly at higher speeds. To keep the wheels in alignment, you have to make sure that the two bolts holding the front end to the back end stay tight. Even with the wheels in alignment, the steering springs mean that the steering is harder to push than it needs to be. If I were given the choice to redesign one thing about this bike, I'd point the steering tubes differently. (I'd point them a little ahead of the point where the rubber meets the road in order to give some straight-line stability and also make them more responsive to steering with a push bar.) One more Shift-specific con: The flange on the front axle that engages the freewheel was welded on a bit crooked on both Shift trikes that we bought, which led to some slightly audible grinding of the freewheel while coasting. My daughter doesn't coast much, though - she's constantly pedaling - so this wasn't a big concern for us. Just a minor quality problem. Overall: If you're thrilled by going 7-8km/h on mostly flat ground, like my daughter is, this is a fantastic trike. Nothing has been better for keeping my daughter active and in shape while having fun as the Mobo Mobito and Shift have.
