What Problem Does It Solve?
If a kids' bike only lets you raise the saddle, the bike can feel cramped once your child grows taller, and you end up looking at the next size up. Besides the seat post, the Sooibe 005 lets the frame itself extend front to back and the head tube telescope, so riding position and reach can be adjusted together across the official 110-180 cm height range. Beginners ride with the training wheels down and fold them up once they can balance, with no need to remove them.
Extendable Frame: Tool-Free Length Adjustment
The frame has an 80 mm scale and is secured by a self-locking tube clamp, so the frame length can be adjusted by hand without tools to set the reach for your child's height.
Telescoping Seat Post and Head Tube
The seat post has a 200 mm scale and a quick-release clamp: turn the small knob to set the tension, then open it to adjust the height. The head tube also telescopes, with its own quick-release clamp for setting handlebar height.
The mixed-age illustration is promotional material for the Sooibe 005 range; the official rider height for the 16-inch version is 110-180 cm.
Fold-Up Training Wheels
The bike comes with patented folding training wheels. With them down, beginners learn to balance more quickly; with them folded up, the extendable frame, head tube and seat post fit riders of different heights.
Tyres and Saddle
WANDA anti-slip all-terrain tyres and tubes, which the brand says handle gravel, dirt and woodland paths, and the thick, wide saddle can be moved forward or back.

Who Is It For?
Sooibe recommends the 16-inch 005 for riders 110-180 cm tall; height is the more reliable guide when choosing. For help matching wheel size to your child's height, see the Jollymap article 6 factors to consider when choosing a kids' bike (in Chinese).
- Good for: beginners over 110 cm who still need training wheels; families who want the bike length, not just the saddle, to adjust; parents who need to fold the bike into a car boot.
- Consider instead: if your child is under 110 cm, compare the 14-inch Sooibe 007 Pro 14" Super Light Kids Folding Bike (official rider height 105-175 cm); for a child who can already balance and wants gears, compare the Sooibe 009 16" 6Speed Super Light Kids Folding Bike.

Jollymap's Advice
The Sooibe 005 16 inch suits children who are already over 110 cm but still learning on training wheels: fold the training wheels up once they can balance, then adjust the frame, seat post and head tube as they grow. If your child can already balance and wants to learn gears, compare the 6-speed 009. Not sure which one fits? Before ordering, chat with us or message our Facebook page with your child's age and height.

FAQ
Where is Sooibe from?
Sooibe (書比) is a kids' bike brand from Hangzhou, China. Its official website lists the company as 書比智能科技（杭州）有限公司, and its range includes mixed-age kids' folding bikes, balance bikes and kids' mountain bikes.
What height is the Sooibe 005 16 inch for?
Sooibe recommends riders 110-180 cm tall, so choose by height; if your child is under 110 cm, compare the 14-inch Sooibe 007 Pro (official rider height 105-175 cm).
What does "extendable" mean?
It means three parts of the bike can be adjusted: the frame extends front to back (80 mm scale), the seat post telescopes (200 mm scale) and the head tube telescopes too. So besides saddle height, the 005 lets you adjust the bike's length and handlebar height.
Does the Sooibe 005 come with training wheels?
Yes. It comes with patented folding training wheels: put them down while learning, then fold them up once your child can balance, with no need to remove them.
How much does the Sooibe 005 16 inch weigh?
9.0 kg (Sooibe official). For comparison, Sooibe's 14-inch 007 Pro is 7.9 kg and the 16-inch 6-speed 009 is 9.2 kg (official figures).
Can I take the Sooibe 005 on the MTR or a bus?
It cannot be confirmed for the MTR: luggage must not exceed a total length, width and height of 170 cm, and Sooibe's official information does not list a folded size for the 16-inch 005. Franchised buses generally restrict bicycles: section 14 of the Public Bus Services Regulations (Cap. 230A) only allows items up to 5 kg and 0.1 cubic metres, and the 005 weighs 9.0 kg, so it does not qualify; minibuses are not guaranteed either. Check the Transport Department Cycling Information Centre page on taking bicycles on public transport and the operators' latest rules.
What is the difference between the Sooibe 005, 007 Pro and 009?
The 005 has 16-inch wheels, weighs 9.0 kg (official), suits riders 110-180 cm, has a frame that extends front to back and comes with training wheels. The 007 Pro 14 inch weighs 7.9 kg (official), suits riders 105-175 cm and also has fold-up training wheels. The 009 16 inch has Shimano 6-speed gearing, weighs 9.2 kg (official) and suits riders 110-175 cm.
