Mongoose Urban Hardshell Youth/Adult Helmet for Scooter, BMX, Cycling and Skateboarding - £4.99 @ Amazon

I got a white one frim the last deal at the same price as a backup & another for a friend, very good indeed - no-braimer at this price.
Might want to measure the circumference of your head just in case, but if unsuitable it's still a great buy as you can gift it to someone with a smaller head, give it away to charity or resell it even for a small profit.

I bought 2 of these at full price last year, and my new ebike I used in the park to get used to it as I am an inexperienced rider, I hit a big tree head on at approximately 30mph,had various minor injuries but the helmet took the full force and did the job brilliantly just a skuff mark on it, great fit and extra thick padding, I highly recommend this product as it possibly saved my life.

Coming up at £19.90 for me...

Awesome just what I was looking for thanks op

Do these hard shell helmets really provide the same level of protection for cyclists as regular helmets?

My son had one of these for ages and they are generally good. At this price very good. The only pain is the straps kept needing tightening.

Is it safe enough?
