2. Mongoose Switch Children’s BMX Sidewalk Bick 18 inch wheel
Great BMX for first-time bike riders
This is a good bike for children who have never used a bike before. It has smaller 18″ wheels and also includes training wheels, allowing children to gain confidence in riding bikes. It is available in a 20-inch wheel version if the children are taller than average for that age group.
Gives children confidence
Aside from training wheels, this bike has a foot brake to allow children to learn to brake confidently. The low frame means that the bike is not too high allowing children to gain balance sooner. The gaining of confidence means that the training wheels should not have to be used for long.
It looks like a proper bike
Unlike some children’s bikes, it looks like a proper cycle once the training wheels are no longer in use. It has metal spoked wheels as well as black grips. In terms of paintwork and colors, it looks like an adult bike, and its performance is reasonable for a first-time BMX.
Cool for kids
This bike is aimed to be the best for children between 5 and 7 to ride and it looks stylish. It looks like a smaller version of the adult Mongoose BMX instead of a kid’s bike. So it does not have childish designs or characters from kids’ TV shows or cartoons on it.
Good safety features
It comes with a foot brake and a wheel guard. Low to the ground, padded grips plus the training wheels for the youngest riders. To put the children in helmets and padding to make sure they are safe.
Pros
- A strong and robust frame means that the bike is safer for children
- The bike is suitable for 5 to 7-year-olds with training wheels and foot brakes
- It comes partially assembled, you only need to put the pedals and wheels on
Cons
- The instructions do not tell you that the handlebar has more than likely been assembled wrong and the left and right stickers may be placed on the wrong pedal.
Sizing Info
- With its 18-inch wheels and optional training wheels, this BMX is designed to be used by children ages 5 to 7.
Who can use the bike?
This is meant for use by children between the ages of 5 and 7. It would not be particularly safe to have children over 7 use. If children between 5 and 7 are heavier or taller than average then it may be worth switching them to a larger BMX bike earlier.
FAQs
Question-1: Does this bike include a kickstand?
Answer: No it does not come with a kickstand, these need to be brought separately.
Question-1: Is it difficult to assemble?
Answer: That depends on whether the handlebar has been put together correctly and the pedals have the left and right stickers on the correct side. Have an Allen key to hand. With an Allen key and bearing in mind the issues with handlebars and pedals, the worst problems can be worked around.
Question-1: How good is the packaging?
Answer: It ranges from poor quality to terrible. Boxes frequently arrive dented or opened with parts missing or hanging out. Check the box as soon as you receive it for broken and missing parts. Then contact the sellers if parts are missing or if there is any damage. People that delay assembling the bike could miss out on the returns or refund deadline.
How to assemble
This bike should only need to have the wheels and the pedals attached to the frame. However, the instructions are not the easiest to work out and Allen keys are not included. In theory, the handlebar should not have to be touched as it has been assembled already though some have been put together wrong and these will have to be reassembled.
The pedals can be sent with the wrong left and right stickers on, or screw holes that are not the correct size. So if the handlebar is not right to reverse it, and if the pedals do not tighten switch the sides over.
Final remarks
This seems to be better if the one you order arrives intact and you are able to follow the instructions. The instructions are not clear and having an Allen key is useful. Once assembled the bike looks good and allows children to get used to riding bikes. It is good that the design makes it appear like a junior bike instead of too childish.
Having said all that if the bike assembles as it should do then you actually have a good quality BMX starter bike on your hands. When the handlebar, brakes, and pedals are set up right then children find it a good bike to learn to cycle on. The learning wheels and the foot brake make it a safe bike while children are learning to cycle. Children find it easier to learn how to keep their balance and gain confidence in stopping should they need to do so.

How to assemble
The assembly for the Mag could sometimes need two people to build it. That can particularly be the case when the brake needs to be set or reset. It can be hard to adjust by yourself, so another person needs to have hold of the brake lines whilst you tighten them.

Final remarks
The Legion Mag provided that it arrives safely and can be assembled without any hitches is potentially a good competition BMX.
