My favorite

Hi folks, I've been riding bikes in the Vermont woods for over 50 years now. Bicycles and motorcycles. The range of riding opportunities with an e mtb is awsome. Most mtb trail networks allow emtb around here. Best of both worlds, the freedom of bicycling and the pwoer of moto. Ride almost anywhere, single track, rails trails, bike paths, jeep roads, main roads. Freedom to ride and no license or registration taxes to hassle with.
I've owned over 50 different motorcycles and over a dozen bicycles, this Ultra FS is hands down my favorite. The suspension is amazingly compliant, especially the inverted fork. Non inverted forks tend to bend under heavy downhill braking, essentially locking out do to stiction. This inverted fork works freely even under severe braking loads. The rear suspension is super too. Motor power is super smooth. The eco and sport settings are very useful, sport giving much more high cadence boost perfect climbing. It is nice to have the eco for road and sport for the trail. Mr. Roshan has done a great job programming this motor.
There have been complaints over the weight of some of these emtb's.
Some claiming that 80lbs is too heavy, some spending more then twice the price of the FS in order to get bike weight below 60lbs. This is due in part to comparing ebikes to bicycles. If you compare the emtb to a motorcycle the ebike is a feather weight. Super light moto dirtbikes are 200 to 350lbs! These ebikes cannot really be called bicycles or motorcycles, they are a unique breed of cat requiring specialized riding technique to operate.
See u on the trail.
Thanks you Biktrix for a great ride!

Love my bike!

We have some pretty aggressive "goat heads" in our area and are having a hard time with the tires. Other than that, these bikes are the BEST!!!!! Absolutely love it so far!

Amazing bike

Great MTB, a little heavy but very solid bike. May have to do some adjustments to your fit but that’s any full suspension bike.
