Fitting Your TM-B 

First step: pick the right top frame size (S or L)

• Since the seat tube and frame are one swappable module, your first fit decision is choosing the right top frame size for your height.

• Set your seat height / position 

  • While standing next to the e-bike, adjust the seat to the height of your hipbone. Tighten the seat enough to sit on it. 

• If needed, loosen one or both of the seat rail bolts and slide the saddle forward or backward. These bolts also adjust the pitch of the seat up or down. 

• Note the numbered marking on the rear face of the seat post for future use. 

• Perform heel-on-pedal test 

  • Sit on the saddle like you normally would.

  • Push one pedal all the way down, to the lowest point it can go (straight down, like 6 o'clock on a clock face).

  • Put your heel (not the ball/front of your foot) flat on that pedal. So your foot is kind of backwards from how you'd normally pedal — heel resting on the pedal instead of the arch or toes.

  • Look at your leg. With your heel on the pedal at the bottom, your leg should be almost completely straight — but not locked stiff. Just a small, natural bend at the knee.

  • What the results mean:

• Leg is straight with heel on pedal → good, that's the height you want.

• Your hips have to rock or tilt to reach it → saddle is too high, lower it.

• Your knee is still noticeably bent → saddle is too low, raise it.

• Adjust cockpit (handlebar) reach

  • Sit on the seat. Without removing the handlebars from their connector, rotate them to find the best angle for your riding position. 

  • A slightly more upright cockpit position can help with low-speed stability and control given the added weight, especially at stops.

• Align each brake lever for proper hand placement. Adjusting to 32 degrees below horizontal is average, but tune them to what you can easily reach

• Always make sure the brake levers can be fully squeezed.

• If you need to adjust, use a 2 mm Allen key to adjust the screw at the base of the brake lever. This adjusts the max distance between the level and the handlebar, to fit your grip. 

The TM-B looks good on you!
