If you have a kid with autism, or possibly some other challenges, you may be in the market for a tricycle that fits bigger kids than most.

One tricycle that fits both a lot of younger kids and can grow for older kids is the “Trikester” by Trek.

Here it is in blue:

and in pink

Trek makes mountain bikes and regular bikes. This trike uses tubing that looks like a regular bike. There is a platform on the back where a bigger kid could stand and use it more like a scooter (be careful with really big kids–like mom’s and dad’s, it is tempting but not really designed for you!)

One of the best parts is that the seat can be moved back–take a look at the picture. See those holes in the top tube where the seat is fastened to the bike? You can move the seat back as your kid grows and increase the seat-pedal distance.

Also, this trike has big, fat tires making it like a all-terrain trike!

It’s worth a look at least. See if you have a Trek dealer nearby so you can check it out.
