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.

    Juggernaut ultra dual 2 with 17” frame

    Bike came well packed. Information needed to assemble was available on line although can be confusing to find. Slight variances in forks displayed in videos versus my build needed closer scrutiny as documentation doesn’t inform you ahead of time which specific fork or other components deviate from videos. Nothing major and the assembly was smooth. As for the bike it is everything I hoped it would be. It does take a little getting used to as to when to shift or when to use the throttle. Of the 9 gear ratios the first 6 are quickly run through whereas the top 3 are the usual cruise gears you’ll run on. I find that on trails rather than constant shifting I can feather the throttle to assist a little more going uphill while in mid gear rather than shifting all the way down to first. May not be totally right thing to do but it works for me and my weak hamstring. I need to boost the front forks as they are soft for my weight but no problem. I am so happy I got the smaller frame but quickly realized I needed to raise the seat for proper leg extension. More engine noise than expected but less road noise with the 3, 1/2” ATB tires. As most do I tried it full throttle and was amazed at what it could do. Have to say it’s everything I hoped for and I hope to put a lot of mileage on it this summer. PS Consider the brake upgrade as I did and you’ll be happy with your decision.

    Good - in every way

    Great web page and easy ordering. Juggernaut Ultra Duo arrived in record time and was easy to assemble with YouTube videos.
    Bike has been fun to ride; lots of power, smooth ride on gravel roads and trails (bought as an “off-road” bike) with no complaints. Great experience with Biktrix.
