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 Duo 3 Step-Thru

    After 2 weeks of ownership all is good.
    I have been travelling and only have 40km on the bike. Assembly was straight forward using your video for guidance.
    The bike works very well, I've had it on asphalt, gravel, and a few trails.
    The bike is stable and sure footed. Anyone that has seen it is impressed with the workmanship and quality of the build. I'm very pleased with the ease of shifting gears.
    For myself 6'3", 200 plus pounds and 75 years of age this step thru Juggernaut was the right choice.
    Thanks Biktrix .

    After what I would call an unhappy wait for the delivery, we got our bikes
    Hub Duo for her
    Ultra Duo 3 for me
    We must say we are very pleased with the bikes, the service the day we picked them up and the apology for the long wait.
    Ryan at the Saskatoon store was exceptionally good as a man to deal with

    Long wait

    We bought two bikes. Hub duo and the Ultra dual 3
    We were told it would be a few
    Days to get them in, only because of the colour choice one one of the bikes.
    It’s been three weeks and the excuse is we have 200 bikes come in to get ready, this is our busy season. If you bought in December we could have it sooner

    I asked if they could try to have it ready for Saturday when we are in town, the answer. NO. We are closed this Saturday for the long weekend.

    Well………. I have owned a couple or three businesses, when it was our “busy season” we worked overtime and 7 days a week to catch up and ensure we had happy customers
    Has anyone any work ethics anymore ?????
    Very unhappy customer!!!

    Awesome ebike

    The Ultra 1000 is a real cruiser…takes the hills with no sweat and the 24x4 inch fat tires are very comfortable reducing many bumps. I also have the extender which still allows room to step thru. I have the smallest extender. The mid drive with torque-cadence is a perfect match. If one can afford the Ultra 1000 go for it, however I think the hub 750 would also be a great second choice. Delivery was only one week. Biktrix support were very helpful on sale and customer tech support have answered all my questions after purchase. Glad I choose Biktrix.thank-you!

    Very Disappointed

    I ordered the Juggernaut Ultra Duo 3 and was notified that delivery would not be until late April 2023. So I joined a Facebook group. Wow. There are many disappointed Biktrix bike owners in Facebook. I found out there customer service was not very good. So I decided to cancel my order since it was not due until late April. By the way this is only three days after I ordered it. Customer service informed me that they were going to charge me a 10% cancellation fee, even though it was only three days after I ordered it and they were not planning on delivering it until late April. So add me to the long list of disappointed people. You can't call me an owner because I cancelled so as to avoid the headaches that so many other owners had. I encourage anyone interested in these bikes to join that group. Biktrix employees are not allowed to be members of the group
