What frame will fit me?

×

The best way to ensure a fit is to check this measurement on your existing bike’s normal riding seat position;

If this measurement is equal to or MORE than the minimum seat height of the selected model then the selected frame size will work, however, if it is LESS you need to select a smaller frame.

 

If you do not have a bike then measure your inseam like this;

For most riders, the frame will work if their inseam is at least 2 inches less than the minimum seat height in inches. For example, a rider with an inseam of 28 inches can fit on a bike with a minimum seat height of 30 inches (30 - 2 = 28).

If you want to have a flat foot on the ground while on a full stop then your inseam must be equal to or greater than the minimum seat height listed for that frame size.


If you are selecting a step-over frame, ensure that the standover height listed is less than your inseam size.

 

    When in doubt, pick the smaller frame. You can always raise the seat up higher.

    What wheels should I choose?

    ×

    Wheel Diameter (Height):

    • 20" / 24" - These wheels offer a lower stance for our shorter customers to allow a more comfortable fit and ride.
    • 26" - A great choice for most riders offering a more traditional look.
    • 27" / 29” - Our tallest tire options for our tallest customers. 

    Tire Width:

    • 52c / 2.125" / 2.2" (MTB) - These tires offer the lowest rolling resistance and best mimic a "Traditional" tire size. They are great for paved trails and commuting, but are not suggested for loose terrain.
    • 3" (MTB+) - A versatile choice for riders who want great performance on both trails and commutes (recommended for ice/gravel).
    • 4" - Fat tires offer great All-Season performance with a focus on stability (recommended for Snow/Sand).
    • 4.8" - The widest tire we offer. Great for off-road and backwood adventures. These tires have lots of tread for extra "bite", extra cushion for riding on rough ground, and added stability while riding on softer terrain (recommended for all-terrain).

    Tread Style:

    • Street Tires - Great for commuting or riding paved paths. Has less rolling resistance than MTB tires.
    • MTB Tires - Great versatility for on or off-road riding. These tires have more rolling resistance but much greater traction.

    New Juggernaut Ultra FS Pro 3

    This is my 2nd Biktrix bike. My first was the Juggernaut Classic Duo. It was fantastic as well but I had decided I wanted full suspension as I mainly ride off road. We are lucky enough to have miles of off road trails to ride here. I typically try to ride 20 to 30 kms a day if I can. The new new Juggernaut Ultra FS Pro 3 has been nothing short of amazing. I have done a number of things to customize it specifically for me but it is awesome!

    Brakes are the weak point. The 4 piston brakes should be standard on a bike this expensive. Also, the single battery really limits the range.

    Too soon to review- initial notes

    A lot to like! A few things to not like. Loved the whole buying experience! The customer support team helped me customize and get exactly what I wanted. Delivery was positive. Fedex came 2 days before schedule. Box and bike in great shape! The bike: just beautiful! Assembled nicely, since all I had to do was the handlebars, front wheel rack and pedals. And seat I guess. First ride. Motor was louder than expected. Kind of a clinky loud. Was surprised that if you try to downshift while pedaling, it stops the motor for a significant amount of time, causing you to lose critical momentum. But the power from the torque sensor, helps make up for any of that. Only a couple rides in. One at night to test the Armageddon light. Super nice so far. I’m sure I will keep testing it. That’s what I got it for.. trails!

    Transformative. My face hurts.

    My face hurts. From smiling too much.
    What a blast it was to ride 16 miles and only using 15% battery suggesting I could get well over 50 miles with the 17AH battery - time will tell. When a hill approached, I kicked it up from Eco PAS 2 to 4 and breezed up the hill. A very steep dirt patch popped up and Sport mode PAS 3 made that lift easy. I did have some electrical issues, but they were resolved over the phone (a loose connector). So far, so good. This beast is strong. High quality. Glad I went with 3" tires - they breach any terrain and are just right for my needs. Now my two ebike buddies want to upgrade their hub bikes (Sondors and RAD) to Biktrix. Very happy with this bike.
