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.

    26x4 fat wheels

    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.

    Bike was defective

    The bike had problems that I could not fix by computer. I arranged to re box the bike and drive 200 mi to Biktrix dealer in Eugene . The dealer "Electric Ave" shipped the bike to you, and are waiting for Biktrix to send the replacement bike.
    They will assemble the new bike there ( costing me $150.00) and I will drive back to Eugene and pick up the bike. I already own a Jug Classic, had it for 2 yrs and love it! put on 2,000 mi.s and still in great shape . I really love my Biktrix bike , that's why I'm willing to drive all the way to Eugene and back "twice" and fork out another $150.00 . Because I know Biktrtix makes great bikes. I'll up grade this rating , after i get the bike. Tim Donohue

    Juggernaut Ultra Duo 2 Step-Over

    The Biktrix company has been very easy to work with. The customer service during the ordering process was very helpful. It was shipped using quality materials. I am mechanically inclined but this was my first bike assembly and it only took about 45 mins. There are only a few things for the buyer to assemble. I've had the bike about 2 weeks now and have put about 80 miles on it. It is clearly a quality built bike with lots of power. I have a bum knee which I am slowly rehabing so on a battery testing trip I pedaled consistently but leaned heavily on the pedal assist with a bit of "throttle only" as well. Averaging about 15 mi/hr, I completed a 34 miles trip with 9% left in the single stock battery. I really like the pannier bags and center bar storage bag. I recommend the upgraded seat. The standard one is ok but my butt was sore after the 34 miles. I put the upgraded seat on and life is good now. One of my students works for a bike shop doing their repairs. He was impressed with the quality and made mention of the problems they have with a number of the other leading brand ebikes.
