Radio have elevated the Evol into a truly unique performance machine, with those oversized logo Radio Rookie tyres really giving the Evol its unique look. This entry-level BMX really has everything you'll need to start making some serious progress. It boasts a Crmo toptube and a sealed integrated headset and mid sized bottom bracket. The frame, fork and bar feature a mix of 1020 hi-ten steel and crmo so the bike can withstand a beating while you're honing your craft on it. Two fresh colourways set this 2021 model apart from the rest with the Black colourway featuring an oil slick sprocket and the Matt Sky Blue colourway going all out on colour. Both colourways feature Radio Rookie tyres with those oversized logos given them that American muscle car feel. ###section### Product Specs FRAME MATERIAL: crmo top tube, 1020 hi-ten WHEEL SIZE: 20" TOP TUBE LENGTH: 20.3" CHAIN STAY LENGTH: 13.2" HEADTUBE ANGLE: 75° SEAT TUBE ANGLE: 71.5° FORKS: RADIO “AM” fork, 1020 hi-ten, crmo steerer, tapered legs BARS: RADIO “AM 20” bar, 1020 hi-ten STEM: RADIO “AM” topload stem, 50mm reach HEADSET: SALT “PRO” integ. headset, sealed ball BRAKE MOUNTS: Welded BRAKES: RADIO “AM” alloy u-brake rear FRONT HUB: RADIO “Rookie” steel hub, lb, 3/8″s, 36h FRONT RIM: RADIO “ROOKIE” rim, single wall, 36h REAR HUB: RADIO “AM” cassette hub, alloy, semi-sealed, 9t, 14mm axle, 36h REAR RIM: RADIO “ROOKIE” rim, single wall, 36h TYRES: SALT 20x2.35, TRACER TIRE SPROCKET: RADIO “VISION” steel 25t sprocket CRANKS: RADIO “ROOKIE” tubular 3pc crank crmo, 165mm, 8 spline BB: Mid size, press fit, sealed bearing PEDALS: RADIO “PRO” Nylon Fibreglass Pedals SEAT: RADIO “CENTURY” mid padded combo seat GEARING: 25/9 WEIGHT: 12.25kg / 27.02lbs ###section### Product Highlights Full Size Bike with a Shorter Top Tube and geometry to Suit riders who are 4ft - 5ft 4" / 120cm -160cm A great all rounder suitable for any type of riding High-quality Chromoly construction Includes sealed bearings Fitted with high-quality aftermarket components

The Solar is manufactured from the highest quality Torayca carbon and is incredibly unique with its 100% monocoque 1pc construction. By using a mono-construction compared to a 2/3pc construction which most other brands use, Radio were able to make the frame even stiffer and stronger and create no weak or fatigue points. The Solar frame is laboratory tested and proven to be insanely stiff and lightweight especially under high impact and stress tests. The internal cable routing allows for a super clean and stealthy setup. ###section### Product Specs MATERIAL: Torayca carbon TOP TUBE LENGTH: 20.75” HEAD TUBE ANGLE: 74.5° SEAT TUBE ANGLE: 71° CHAIN STAY LENGTH: 14.25” BB HEIGHT: 11.6" WHEEL SIZE: 20" STANDOVER HEIGHT: TBC DROPOUT SIZE: 15mm HEADSET TYPE: Integrated tapered 1-1/8” – 1.5” BB TYPE: Euro SEAT TUBE DIAMETER: 27.2mm BRAKE MOUNTS: V-Brake WEIGHT: TBC ###section### Product Highlights BMX Racing Specific Geometry Race Specific Frame Strong and lightweight Internal cable routing Tapered tubing
