KAKUKA K26 FAQs

1. Suspension Fork

Q. What is the length of the K26 Suspension Fork?

A. K26 designed with 100mm front fork, featuring lockout switches. It’s lightweight, efficient and allows the wheel to get out of the way when it needs to while offering enough support to keep you from bobbing through the travel up a tough climb.

2. Disc Brakes

Q1. Disc Brakes vs. Rim Brakes?

A1. If your budget allows it, it is best to buy a bike with disc brakes. Disc brakes have better control, power, and consistency in all weather conditions than rim brakes.

Q2. How do I maintain the disc brake?

A2.

1. Adjust the calipers – Misaligned calipers cause friction through the rotor and pad rubbing. You can adjust caliper alignment using just a 5mm hex key and a rubber band.

2. Brake pad cleaning or replacement – Using a 5mm hex key and disc brake spacer, you can remove the brake pads to clean or replace them. Use isopropyl alcohol for cleaning the pads and rotors.

3. Rotor texturizing to restore performance – If your rotors become shiny after some months of use, you can lightly sand the rotor with 200-grit+ sandpaper until it has a dull look again.

3. Tire

Q. Could the K26 be replaced with a larger size tire?

A. K26 designed for 26'' x 1.95 wheels. 26'' was the wheel size standard for decades. Currently, we do not accept changes to wheel sizes, also DIY would void the warranty.

4. Shimano Shift Gears

Q1. How to shift gears?

A1.

  • Changes in gradient – Low Gear = Easy = Good for Climbing; High Gear = Hard = Good for Descending.'' Moving the chain closer to the bike makes it easier, and moving the chain away from the bike makes you faster. ''

Low Gear

1-3 level

Big Ring

Easy to up hill

Small resistance

High Gear

4-7 level

Small Ring

Hard to pedal, good for down hill

Big resistance

 

  • Sharp corners – If you must slow down considerably before cornering, shift to a lower gear so it is easier to accelerate again when you are clear.
  • Traffic stops – If you are approaching a stop sign, yield sign, or traffic light, shift to an easier gear so you can accelerate smoothly when necessary.
  • To ride out of the saddle – Shift up one or two gears higher to maintain a steady cadence when you want to ride standing up.

 

Q2. When should I shift gears on my bike?

A2. Anticipate the terrain: Shift right before you start climbing, not halfway up when you're slowing rapidly and applying maximum pressure on the pedals. If you do shift on a hill, shift one gear at a time, and momentarily relax pressure on the pedals as you're shifting.

Q3. What gear should I use on a flat road?

A3. For riding on flat roads, it is recommended to use the middle gear (3-Level). It is a common choice among bikers as it helps you reduce pressure from your feet onto the pedals.

5. Customizable parameters

Q. How do I change the limmted speed ?

A. In Europe, most e-bikes are limited to speeds of up to 25 km/h (15.5 mph). Therefore Kakuka provide the option to change the limited speed.

When the bike exceeds the setting speed, the controller will stop the outputting of the motor to protect the riders. The optional speed setting range from 12 km/h to 32 km/h. The default Max speed is 32 km/h.

Please press UP and DOWN to change the value, then pressing Mode to confirm,entering into the next setting.
