The MAXXRAXX 4 Bike Premier Cycle Carrier / Bike Rack is robustly built from structural steel. It carries 4 bikes (can extend to 5) with a maximum load capacity of 80kgs. With a tilting facility, an inbuilt security cable, a unique ratcheted tie down mechanism with pins and 2 padlocks provided for added security. There are also two webbing straps that can be attached to roof rails for added security. Very easy to put together and I can provide instructions. There are videos on their website that show how easy it is to put the rack together. Please note the tow bar attachment supplied with this rack is for a fixed or detachable 2-bolt flange tow bar NOT a Swan Neck tow bar, this uses a different attachment which can be bought from maxxraxx.co.uk. Two fixing bolts are will be needed to attach to the towbar which can be bought for around £5 or maybe even less from a hardware store. These cost £200 new so grab a bargain!
