Silver streak

As it is winter here in British Columbia I have only put on about 20 km! So far very impressed with the power and very smooth suspension. Looking forward to hitting the trails soon

Not my first rode

I have been enjoying the original Juggernaut Ultra FS since early 2018,
now with over 17,000 miles.
Took advantage of a great offer for the Juggernaut Ultra FS Pro 3 Mullet and received it this January ’25. With the additional range extending battery. I hope to ride longer and explore our back country here in California.

Thanks to the Biktrix team for making me happy for many more miles to come!

Bike is fine, but return policy is horrible

Bike is heavy and clumsy. Very powerful, but steers like a tractor trailer and is heavy like my dirt bike. Trying to return the bike costs $550 return fee, PLUS a 15% to 50% restocking fee, which they decide when they receive the return. This policy was of course nowhere to be seen when ordering. Utter nonsense. I hate the company more than the bike.

Shipping e-bikes is unfortunately not cheap. You are welcome to ship the bike by yourself to us - we can then waive the $550 fee. You'll see that FedEx will charge you over double what we are quoting.

Btw, which dirt bike are you comparing with that weighs less than 100lbs?

Awesome Ebike

This Full Suspension mid-drive MTB Ebike is incredible. Great ride with lots of torque to climb hills. The hydraulic breaks are solid. They can stop the bike quickly if needed. I have had the bike for a couple of weeks and I am thoroughly impressed. Great purchase. Their sales and customer service support is very good. 👍

After a month now.

It's not easy to give a review with a brand-new bike with only just over 100 miles on it. Buying a new bike this time of year here in the NW of the United States we don't get to ride much being the weather sucks your soul more than you can ride. I find the quality and finish of the bike is very good. Very solid in every way. It's a bit slow in the first 2 PAS modes for my comfort. But understanding how much volts it uses, or let's say how much it doesn't use on the batteries is a plus. But a bit slow. If you put the bike in PAS 3 and above it does fine with keeping pace with others. I'm 5'8 tall. I got the smaller frame bike 17 I think is what it is. I have to raise the seat fairly high for my legs to be comfortable riding. So, it makes me feel like I'm kind of high over the bike. I'm sure over time that should calm down for me. I like the bright yellow color I choose for the frame. The black accent help with the overall look of the bike. The A bar was to flat for my liking. I gave it to a sibling to put on his bike. I bought the real Jones Bike H bar with a 2.5 lift. It feels a lot better on my shoulders. I'm getting use to the Wrem front forks and the Wren rear hub. I got help from Tej with programing my Ultra motor. I thank him very much for his help. The small change in programing I think will help the bike overall feel and keep me wanting to ride the bike more than the other 3 ebikes I own. I would like an invite to review the bike maybe this time next year. And see how many miles I get to put on it by then. Overall, I would recommend buying this bike if you want a large hunting frame bike that is very comfortable with full suspension and is powerful in higher PAS. But with city street manors. I went with the 26x4 inch fat tires. for riding in nearly all conditions. It will with ease.

The crank arms stripped out.

I like the bike. Would be awesome, but the crank arms threads stripped out where the pedals go. I had the bike for barely a weeks. Rode it three times for a total of 12 miles. Biktrix is working on a solution for me. I tried changing the arms myself, but my universal puller is not working on the arms.
