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.

    If you need help with this, feel free to send us a note.

    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.

    Awesome bike

    I was a bit intimidated by the size and power of the bike on my first short outing. Second time out was perfect. I loved riding it and didn’t want to go home. The peddle assist is amazing. I only used peddle assist 1 as it was more than enough assistance for most of the ride but you sure appreciate the higher assists on steep hills. You definitely want to have mirrors on the bike for road riding though. You can get moving pretty quick and want to be aware of other vehicles.

    DERAILLEUR

    I am happy with the bike as a whole, however the derailleur needed major adjustments. this resulted in a broken chain, repair costs, and now the bike is in the shop for a derailleur job for additional cost.

    Really, enjoy the bikes

    Good range, power and comfort I think I’ll probably upgrade to a suspension seat post and I wouldn’t mind the upgraded brakes in the mountains. You get to going downhill pretty fast and I worry about overloading the brakes.

    Juggernaut Classic Duo Step-Through VS Rad Rover 5

    I bought the 'Bixtrix Juggernaut Classic Duo Step-Through', as an upgrade to my 'Rad Rover 5'. I live in an area with steep hills. The mid-drive motor lets me use the gears, and it makes a world of difference. The motor is a true 750 watt, that peaks at 100 watts. As compared to the 500 watt motor in the Rad, that peaks at 750 watts. It feels like twice the power, the thumb throttle nearly pulls the front wheel off the ground. It has the 18-1/2" frame and I am 5'-6". I can put both feet on the ground, and the seat could be lowered another 2 inches. The step through height is lower than the Rad too. The 3" x 27-1/2" tires are fine for off road, and have noticeably less rolling resistance. I'm very happy with the bike and the support from Biktrix.
