18" fits riders 5'5" | 30in inseam and taller (In Stock and Shipping)

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 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 are Purchasing a Step Over Frame, Make sure your inseam is above the stand over measurement as well. 

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 (great on snow | sand | gravel)

    What wheels should I choose?

    ×

    26x4.8 The widest tire we offer. Great for Off Road and Backwood adventures. Lots of tread bite for traction and width for cushion on rough gound as well as stability on the softer stuff (sand/snow)

    26x4/24x4/20x4    4in Fat tires are a verstatile choice. Great for on road and off. All season riding.

    24x3 (depends on tread, street or mtb, use the below rim size bit along with applicable tread type bit from below)

    20x/24x smaller wheel rim allowing for a shorter overall bike, great for riders who are not tall. Check the over bike measurements to choose the right size for you.

    27.5x3 A versatile choice, more agile than 4in option.Great for trails and commutes. Not recommended for sand or snow.

    Street tire - great for commuting or riding paved paths. Less Roll resistance. 

    MTB Tire- Great versatility. On or off road. More “bite” from the tread to

    Biktrix Are Awesome!

    We definitely made the right decision after extensive research. There are similar bikes on the market but be wary as some are pretty sketchy operations. Biktrix bikes are high quality - you pay for what you get. Customer service has been great and have gone out of their way to answer general questions and help with a billing issue created by PayPal. Just a warning - if you are located in Canada, when purchasing through PayPal make sure your VPN and obfuscation software is off!

    For Me the Bike is Great

    I bought this bike because my knees are in pain and I need the exercise to strengthen the leg muscles as I need surgery. I find it painful to walk and stand for any time on my legs. I have an old 5speed bike and I was having a difficult time pedalling up small inclines and had to sometimes push my bike up these small inclines and up all the steep hills. With THis Ebike the pedal assist is amazing and I have had no problems at all pedalling. I also have used the throttle and was amazed at the power and speed that you can get out of this bike.
