The Academy Inspire is an 18" kids BMX Bike which is the perfect stepping stone for 7-13 year olds before they get on a full size 20" BMX. For an entry level BMX the Inspire is more than respectable when it comes to design and spec. The frame is built with a CrMo downtube to reduce weight, and Hi-Ten steel forks for durability. The 18" top tube is paired with 18x2.1" tyres for a smooth ride that is ideal for smaller riders. The 3 piece CrMo cranks, sealed mid bottom bracket and fully sealed cassette hub with 9t driver are a mark of the Inspire's quality, sure to last as your kids grow. The Academy Inspire is a great bike for learning and growing BMX skills, suitable for the advanced little shredder or someone just starting out.
