Kids bike capability

At the beginning of spring I got my daughter a trek roscoe 20 inch. It’s a mid fat bike with 2.8 tires. She loves it and has gotten pretty good on the trails. I want to keep our rides fun. I know adults use 4-5 inch tires for snow and sand rides. But she is much smaller than an adult. She is 3-10 and 42#. Do you think that her 2.8 tires would work for sand or snow? Any tips on how to make that work? Or is this a really bad idea

Some sand and snow, yes it should be fine. I think biggest issue is even with a fat bike those conditions require more finesse to not spin out, which may be difficult for a little one but if rides are reasonable and she is having fun then its all good.

best tip i can think of is make sure she is running the optimal tire pressure for every ride, this makes a huge difference for me when riding snow. Less pressure than needed feels slow and squirmy, too much and not enough traction. Start with smaller/ shorter rides or easy bail out options and work up slowly.

Have fun!

Thanks that’s what I was thinking. Any tips on what pressure it should be at?

There is a sports field close to the house we would start in. Just do some circles till there is confidence. Also to make sure it’s fun for her. We can always go back and get the sled.

If the trail is fairly rocky i go to the low teens to avoid rim damaging hits, packed snow around 10psi, softest snow that is still rideable i do about 4 psi. Although i am 200lbs, on 26x4 tires. But i might venture a guess those pressures arent too far off for a much smaller person on much smaller tires. Sorry my kid is still on a strider so I don’t have any better info to share.
That’s great information. I am supposed to get my first fat bike tomorrow just in time for winter. I definitely want to try the snow. But I am really looking forward to the sand as my parents still have a house at the beach. My 6 year old will also get a kick out of it. But I am pretty sure her bike will end up in the ocean

Just fyi so you are not disappointed (in case you don’t already know) i would say once you hit about 6” of fresh powder even a fat bike will struggle. 5” tires would do a bit better than my 4” but not drastically. At that point you just need to find some packed snow. Snowshoe tracks work great. And it is a ton of fun!

I have no idea what I am getting into. I just wanted to try something new. I might not like it and move on. We can use a extra trail bike for family outings anyway so I don’t have much to lose. My kids can’t ride away from me yet so I don’t need another fast trail bike. Going slow can be fun also.
