New specifications for next-gen FX5

FX started as a kind of motorized mountain bike but after extensive testing discovered that even the most extreme Downhill bicycle suspension, brakes, wheels, tires etc. were not capable of the kind of performance and durability our test riders and customers wanted.

So now there are virtually zero bicycle components on our new FX5 models, except for the Downhill handlebars!  It’s been a major development job to keep the ready-to-ride weight anywhere near our 125 lb / 57 kg target, but we’re very close.

They also know their enduro and trials bikes, and now they are discovering all about the super-lightweight world of Mountain Moto!
