Description

The Royalbaby Children Rider Bicycle RB14B-6R boasts a robust steel frame that ensures durability and stability. The 14-inch wheels are perfect for young riders, providing a low center of gravity that helps prevent tipping. The bicycle features a 6-speed Shimano derailleur system, allowing children to learn how to shift gears as they progress in their riding skills.

The front and rear V-brakes offer reliable stopping power, and the adjustable seat height allows the bicycle to grow with the child. The training wheels can be removed as the child gains confidence, transitioning them smoothly from a beginner bike to a more advanced one.

Adjustment and Maintenance

Refer to the content of brake adjustment and maintenance in this manual and videos on brake adjustment.

Stem Assembly and Adjustment

If the expander bolt cannot be screwed tightly, please take out the stem and check if the bottom wedge (a) (metal pieces of castings) falls into the head tube. If so, please tip out the wedge (a) from the head tube and then screw it to the expander bolt and insert it into the head tube again when the distance to the bevel connection of the stem is 2 3mm. Then use the spanner T1 to screw the stem tightly in a clockwise direction. The handlebar should be to be vertical with the front wheel before screwing. ( As shown in the figure 1)
What to do if the handlebar is not flexible or too flexible when turned left and right? Unscrew the head lock nut (b) in a counter-clockwise direction by using an adjustable wrench, and slightly unscrew the top head race (c) in a counter-clockwise direction (or screw to tighten in a clockwise direction) to test the tightness when turning the handlebar. Repeat the steps if necessary until the tightness is appropriate the last step, screw the head lock nut (b) tightly. (As shown in figure 2)

Using and Adjusting the Brake

The left brake lever controls the front brake, and the rear brake is a coaster brake.

Adjustment of V-Brake
1. If one side of the clearance of the brake block is smaller than that of the other side, screw in the adjustment bolt (d) or screw out the adjustment bolt (d) on the other side. Then test the brake lever to see the effect. Do the adjustment again if necessary, until the clearance of the two sides is the same and the brake works well.
2. If the clearance of both sides is too far or too close (should be within 1-3mm), the brake cable adjustment screw (e) should be loosened. Then use one hand to press the two brake blocks to the right position and pull the brake cable tight. Secure the brake cable adjustment screw (e). Test the brake. Do the adjustment again if necessary until the brake works well. (As shown in figure 3)
Adjustment of Caliper Brake
- If the clearance of both sides of the brake block is too far or too close to the rim, loosen the cable adjustment screw (f) fixing the cable end.
- Then use one hand to press the two brake blocks to the right position and pull the brake cable tight. Secure the brake cable adjustment screw (f).
- Test the brake.
- Do the adjustment again if necessary, until the brake works well.
- On the occasion that one side of the clearance of the brake block is smaller than that of the other side, tighten the brake fixing nut (g) on the rear side of the front fork below the head tube of the frame to get the brake block to the right position.
- Test the brake lever to see the effect. Tighten the bolt again or slightly loosen the bolt if necessary until the clearance of the two brake blocks is the same. (As shown in figure 4)
Adjustment of Band Brake
1. If the rear wheel can still rotate when the brake lever is held tightly, firstly use the spanner to screw the adjusting nut (h) of the brake cable tightly, and then test the flexibility of the brake.
- If the brake is still not so flexible, use the screwdriver to loosen the cable adjustment screw (i), and then tighten the brake cable and the cable adjustment screw (i) at the same time.
- After that, release your hands and test the flexibility of the brake again. To get the optimum status, adjust it repeatedly to ensure a suitable length of the exposed brake cable.
- Since the working principle of the brake is to restrain the rotation of the wheels by drag force due to friction, the brake block may be worn out after a period of use, thus the brake would not be so flexible.
- Under such conditions, adjusting nut of the brake block m should be adjusted by a screwdriver. The brake would be more flexible if you screw it more tightly. However, the brake block should not hold the brake drum when it is not braked. (As shown in figure 5)

How to Adjust Training Wheels

As shown in Figure 6)

You can adjust the position of the nut and bolt (k) which connect the training wheels and training wheel lever to an appropriate height.
The clearance between each training wheel and the ground shall not exceed 25 mm with the bicycle supported upright on a flat horizontal surface. Low clearance between the training wheels and the ground may result in the rear wheels turning without moving forward when cycling on a rugged road or riding with low tire pressure.

Adjustment of Daraillaur

Place the chain on the smallest sprocket (I), and adjust the High limit screw so the idler roller (m) and the smallest sprocket (I) are lined up vertically.
Then place the chain on the largest sprocket (n), and adjust the Low limit screw until the idler roller (m) and the largest sprocket (n) are aligned vertically.

(As shown in figure 7)
