Description

The all new CHASE Edge is a race ready BMX machine, ideal for riders ready to get serious about BMX racing and take it to the next level.

Just when you didn't think it was possible, the new Edge has been improved, as now it is equipped with Shimano Hydraulic disc brakes (Junior size & above), all new Chase 24mm 2 piece Alloy Cranks (Expert XL & Above) , updated gearing and crank sizes, a 2 tone paint and graphics design, and an closed rear dropout system with integrated chain tensioner system,. The Edge frame also features hydroformed, triple butted, 6061 aluminum tubes with an integrated head tube. Other featured parts on the Edge include 4130 chromoly fork and handlebars, double wall rims with triple engagement rear cassette rear hub, and TIOGA tires. The combination of all these components arguably makes the CHASE Edge one of the most advanced race BMX bikes available today.

The new Edge also features a two tone paint design, along with waterbed decals that are under the clear coat. Using some of the best brands in BMX to build up the Edge, we feature Pro level parts on various sizes of the Edge including Tioga tires, Chase 2 Piece 24mm Cranks, Insight Chain Ring, Shimano Brakes, a Triple Clutch System cassette hub, KMC Chains, and a Pivotal Seat and Seat Post. With 9 bike sizes offered, the Edge line up gives you a full range of size options for just about any size / age racer.

As one of the only Micro 18 inch race bikes on the market, we have no doubt these will be in hot demand for the 2026 season. We wouldn't be hanging around thinking too long about picking one up for your youngest shredder, these will sell out quickly!

Features

One of few 18" race bikes. A proper race build in Micro 18 size, so the youngest racers get real gate equipment rather than a scaled down toy.
Hydroformed triple butted alloy frame. A 16.25" top tube in 6061 T6 with an integrated head tube, enclosed rear dropouts and a chain tensioner system built in.
Chromoly fork and bars. Full Cr-mo forks with tapered blades and Cr-Mo bars at 2.25" rise and 20" wide, sized for small hands and shoulders.
Mechanical disc brake. A 140mm rotor with Shimano B01S compatible pads gives light, predictable stopping power that small hands can actually use.
Triple engagement cassette rear hub. Three pawls at triple angle engagement for 24T ratchets pick up power quickly, sealed and laced to double wall rims.

Assembly information

Your race bike ships mostly assembled in the box. Finishing it takes most people 10 to 20 minutes with basic tools, and the video above walks through every step.

Fit the handlebars and line them up with the front wheel
Fit the front wheel, pedals and seat post
Spin the rear wheel and check the rotor runs clear of the calliper
Check the brake and tyre pressure before the first ride

Disc brakes: keep your fingers off the rotor and pads, because oil from your skin contaminates the braking surface and takes the bite away. If the rotor rubs, loosen the two calliper bolts, squeeze the lever, then tighten them again with the lever held on. Bed the brake in with a few firm stops before you race it.

Tools: Allen key set and a 15mm spanner for the pedals. Check your axle hardware, since race bikes vary between bolt-on nuts and a thru-axle.

Rather have it done? Ask us about extra assembly before you order, or any local bike shop can finish the build for a small fee.

Race frames are sized by class, and the class you ride is set by rider height rather than age.

Size	Rider height	Top tube
Micro (18" wheels)	Under 120cm	16.25"
Mini (20" wheels)	110 to 140cm	17 to 18"
Junior	120 to 150cm	18.25 to 18.75"
Expert	130 to 170cm	19.5 to 19.75"
Expert XL	145 to 170cm	20 to 20.75"
Pro	150 to 175cm	20.25 to 20.75"
Pro XL	165 to 180cm	21 to 21.25"
Pro XXL	170 to 185cm and up	21.5 to 21.85"
Pro XXXL	175cm and up	22"
Pro XXXXL	180cm and up	22.5"
Cruiser (24" wheels)	175cm and up	21.5" and up

Heights overlap between classes on purpose. Where you land in two, a growing rider is usually better on the larger, and a rider who wants the bike to turn faster on the smaller. Some brands label the Pro size Pro L, with the same fit.

How to measure

Stand your rider against a wall in the shoes they ride in, heels flat, and mark the top of their head. Measure from the floor to the mark.

Between two sizes and still growing? Take the larger size.
Racing gates and wanting the bike to turn faster? Take the smaller size.
Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

Not sure? Send us their height and we will tell you what we would put them on.
