I don’t know of many that go smaller from there either. Hopefully some training will allow him to be able to climb on his own for some of the ride. Sticking to flat nordic type trails for fat biking in the snow might be our best bet. Really, this frame is most likely a back up bike for a family of enthusiasts that want their child to join the fat biking they do in the winter. While the Mongoose Argus Trail is trail worthy, there are other bikes that do trail riding better. There is a low level shimano hydraulic disc brake kit mongoose racing bike that is SO NICE compared to the cable disc brakes.
When break-in didn’t help, I installed Shimano SM-RT56 Disc Brake Rotors (6-Bolt, 160mm) and Shimano BR-M375 Disc Brake Calipers. Was tempted to go hydraulic, but didn’t want to spend the money for possible over-kill. My son was apprehensive to let loose with the rigid platform. He did say that he noticed a difference in the handling with the big tires and it felt kind of like his Kawasaki KLX 110.
Mongoose has given the “go-ahead” to do a long term review mongoose racing bike to assess the handling and function of the Argus once winter comes. So if you’re curious about how the bike performs in the snow, stay tuned….. Since our founding BMX has been the cornerstone of who we are.
Luckily, we have tow ropes to mitigate the complaints. My son has grown to like down hill riding better than cross country. When we climb he lets the complaining come flying out. Mongoose utilizes house branded parts to cover contact points like the grips, pedals and seat.
Mongoose offers an array of models that are specifically designed to suit different riders and terrains. Here are some top models in the Mongoose fat tire bike series that you might consider. With that said, the mongoose dirt bike bike handled as a fat bike should.
