KAKUKA K70 Electric Bike | 700C Electric Flat Bar Road Bike

• *The range and top speed listed for e-bikes are based on a professional cyclist weighing 60kg riding with the 1 level pedal assist in urban areas.
• *The performance will vary with rider weight, cargo weight, rider /cargo shape (both contribute to drag), terrain, tire pressure, brake adjustment, throttle vs PAS usage, pedal power, battery charge level, ambient temperature, and wind conditions. Under certain conditions, it is possible to get ranges and top speeds that are different from the listed estimates.

KAKUKA K70 FAQs

1. Flat Bar

A. K70 is equipped with the 660mm flat bar, which is the most basic and classic style of straight handlebars. Flat bar handlebars are designed for recreational riding and city commuting.

2. Disc 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.

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

A1. K70 designed for 700c x 32c tire. 700c signifying that the diameter of the wheel/rim is 700 mm, the 32c describes the diameter of the tire when inflated.

A2. Most road bikes come with 700c wheelsets. 700c x 32c tire is relatively large for a road racing tire, as the commonest sizes for these is 23-28. In comparison to the 23c-28c tires, the 32c has more volume. You can run the tire with less pressure and not worry about pinch-flatting (hitting a rock, curb, pothole or similar and having the tire compress so much that the rim hits the object, pinching the inner tube and thus causing the tube to rupture).

4. Belt Drive

A1. Compared to the chain-drive, the belt-dive is cleaner, more durable, less maintenance. That’s why the belt-drive became more popular in the industry. On average belt drives last four times longer than a chain drive before they need replacing (20,000 vs. 5,000 miles).

A2. A belt drive bike uses a continuous toothed belt made from resilient synthetic materials such as nylon and carbon fiber. The belt drives two plates in a straight line with one front chain ring and one rear cog. These plates are usually made from metal alloys like stainless steel that add to the system’s durability.

A3. It is recommended to rinse it off (just keep your sprayer away from your bike motor), or wipe it down with a sponge, or use the toothbrush (especially if there’s gunk in the belt’s teeth). Just get any obvious debris and buildup off the chain and you should be good to go. Your belt never needs lubricant and it won't rust.

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.
