Three steps to make your e-bike more comfortable

After you finished assembly of your HJM e-bike, next step is to adjust it for comfort. Here are three steps for your reference. Please be patient while adjusting your e-bike for comfort.

Step 1. Seat

Saddle height, the distance between the bottom bracket and the top of the seat, plays an important role in comfort, overall performance, and injury prevention. So finding the right saddle height is critical for each rider. Fortunately, almost each HJM e-bike is equipped with an adjustable seat and seat post.

1. Tools

A set of Allen wrenches ranging from 3-6 mm

A torque wrench with a set of bits

Loosen the seat adjustment bolt beneath the seat with the right wrench when adjusting seat. Don’t remove the bolt fully or take the saddle off completely.

2. Adjust the Seat Angle

Adjust the saddle roughly parallel to the frame with nose slightly down. That's within 6 degrees of the level, normally 0 to 6 degrees.

3. Adjust the Seat Height

To set your saddle height, sit on your bike and place your heel in the middle of the pedal shaft at the farthest point so that the crank is in line with the seat tube. Your legs should be straight and do not touch the pedal by shaking your hips (sit straight!).

Please try to put your feet on the floor. You should be able to touch the ground with the tips of your toes and still keep the bike straight

Removed the seat post up and down slightly to adjust to the best height.

Don’t forget to tighten the bolt after adjustment.

Step 2. Handle bar

The height of a bicycle handle is important for the comfort of riding, wind resistance and safety. HJM e-bikes reserve a certain adjustable length for the front fork pipe.

2. Process

Loosen the stem face plate bolts. Don’t move it.

Adjust the handle bar to your height. Set the handle bar in the right position up and down according to your riding habit. Your weight and power can be distributed over them will be better. The number of front fork pipe washerscan beincreased or reduced if necessary. 

Tighten the stem faceplate boltsevenly 1/4 turn at a time. Turn the handlebar from side to side to ensure there is enough cable slack. The handlebar should turn fully to each side without pulling cables taut. You can't turn the handle bars if you screw it too tight.

Step 3. Brake lever and shifter

Angle and position of the brake lever and shifter are also adjustable. If the brake lever is next to the shifter, it will cause excessive upturn of the wrist when riding, which will lead to fatigue after a long time. One the contrary, it will be not easy to handle them, thus affecting the braking effect and safety.

2. Process

Loosen the brake lever clamp bolt on the underside of the brake lever. Don’t remove it.

Adjust the angle of the brake lever and ensure the lever is easily accessible to the rider. Tighten the brake lever clamp bolt. Torque the bolt to the recommended value listed in your owner's manual.

Repeat steps with the other brake lever.
