Simply the best

This bike is unreal, first impressions are great, the bike rolls, everything is smooth and sturdy, the component's are all really good branded stuff all round. Up hill it's a little on the 'hard work' side but still the gearing is low enough to make it manageable. Downhill is really where this comes alive, the suspension is elite, no matter how hard I pushed or how many stuffups I made the bike soaked up everything I threw at it, at no point did it feel like I was getting shaken or bucked around by the bike, even on casing/overshooting jumps, gnarly rocks and big drops at speed it still felt like I was riding on a silk path and went in what ever direction I desired, in the air this thing glides like a hang glider and is easy to pitch in your desired direction. Tight technical slopes are also no issue as it's balanced really well and there is an insane amount of grip on the stock tires. As for the aesthetics that to is really nice, most of the cables are hidden in the frame and the bike is built it a way where you could interchange components really easy to personalise it for yourself, in a nutshell it's very compatible as it already runs heaps of aftermarket parts. Overall: best money I've spent in a long time, it's an absolute beast on the trails, perfect for beginners and pros, to say this is a 'budget bike' really takes away how good it is as in my opinion this could easily compete with any of the common brands. I'm a whopping 176cm tall and 69(nice) Kgs, went with the medium and it I fit it perfectly, if you're on the cusp of sizing I'd size down as it's a bigish bike. Also side note I brought the wrong size to start with and bikesonline were super easy to deal with to get it sent back and get the right size and postage was incredibly fast, had the bike within a week both times, brought it on the Friday and it arrived on the following Wednesday 10/10 for them too

Such an Epic Enduro Bike

I've been riding this bike for a while now and even though I was a bit sceptical with the weight this bike feel absolutely amazing on the climbs and the Downhill. This bike just like the speed and eat up all the chunk. I've put it to the test over Angel Fire Bike Park and it performed like a Bike Park bike absolutely a shredding machine. Highly recommended. The only thing I upgraded was the brake levelers for some cheap SLX and perfect breaking power.
