Specialized Riprock Coaster 16 Kids Bike 2021 - Black/Emerald Information

Season : 2021

Brand : Specialized

Code : B6517-9707

Beeline: The Specialized Coaster 16 Kids Bike - available here in black and also available in pink - is a popular kids bike with 16 Inch wheels and comes with the option of stabilisers for a fun, light and tough kids bike. The bike comes fitted with stabilisers, but if you want these removed then no problem, we can do this for you. The bike features a coaster pedal back brake, meaning the brake is activated when pedalled backwards, and has wide 2.3 tyres for a cushioned ride that offers great stability. And it's tough too, able to stand up to abuse from more than one child! Made from the same aluminium that Specialized use on their adult mountain bikes means that the bike combines lightness with robustness.

Specialized: With our riprock coaster 16 riding gets boiled down to its simplest element: fun.

And to make sure of it we designed the bike with tons of cool features that our easy for your little ones to use like a coaster brake for simple stopping wide 16x2.3" tyres that increase stability and confidence and tough components which will stand up to years of abuse.

It's the perfect bike for your little ripper to start getting out on the trail withwe just wish that we had one when we were kids

Key Features:

  • The premium A1 aluminium frame is lightweight and built to withstand the tough use by kids, while the geometry features an ultra-low standover that makes it easy for your little ones to fit on and grow with the bike.
  • 16x2.3" Rhythm Lite tyres deliver tons of traction, comfort, stability, and fun over all types of terrain. 
  • Steel coaster brake is a reliable, easy to use brake perfect for safe stops and awesome skids.


The measurement of kids bikes is mostly based on the wheel size. Whereas an adult mountain bike uses 27.5 to 29 inch wheels, kids bikes range from 12 inch wheel through to 26 inch. Although the manufacturers offer a guideline as to which ages the models are intended to fit, it is just that: a guideline.
Balance Bikes – the balance bikes we stock are made from aluminium, but still light and durable too, so you can pass it down to siblings. These allow the kids to gain confidence and scoot around on them.
14” Wheel Bikes – Predicted age range 2-4 years old: These come equipped with stabilisers and some models use a pedal back brake to allow the child easy braking when needed. The frames are lightweight aluminium offering durability.
16” Wheel Bikes – Predicted age range 3-6 years old: The 16” wheel bikes also come equipped with stabilisers, but these can be removed should you wish. The frames are lightweight aluminium offering durability.
20” Wheel Bikes – Predicted age range 5-8 years old: There are different versions available here; some models have a suspension fork like on a mountain bike, which adds weight, but tackles bumps and knocks with greater ease. The rigid fork lacks the bump absorption but reduces the weight of the bike significantly. These are normally equipped with 6 gears.
24” Wheel Bikes – Predicted age range 7-11 years old: These are the biggest sizes of kids bikes these bikes move onto triple chainset, giving the bikes 21 gears, and a real mini mountain bike feel, complement by the suspension fork and V-Brakes. A rigid fork version saves a significant amount of weight.
The Next Step – Smaller Size Mountain Bikes: For teenagers we normally find smaller size mountain bikes, such as 13.5”or 15” mountain bikes are popular, as are 26" wheel bikes.
