OK Bike with the potential for greatness

These days, it's cheaper to buy a complete bike than to buy a frame & fork set. So... I set out looking for a bike that had what I wanted at the cheapest price. I'm a hefty guy, so no carbon fiber for me... which means Throne and Cyborg are a no go. I wanted a thicker styled frame in 100% 6061 alloy. It came down to Golden and 6ku. 6ku has a decent reputation at this price point and.... there was a bit of a discount when shopping directly on their website.

Fast forward, the bike arrives, well packaged. The frame is well built, the tires are blah... standard issue Kenda tires with Kenda tubes. The Tektro breaks, again blah... actually my front break had a bad paint job, but all else was functional. The rims are OK, but the back rim is slightly out-of-round, which my local shop fixed up for me. Also the bearing nuts were way too tight out-of-box and not adequately lubricated. I fixed that... The chain is cheap and will stretch quickly (see above where I mention that I'm hefty) but it will do for now. 1 of the hex nuts for the rear wheel was stripped, out of box; luckily I had spares. The plastic pedals are a joke, I bought some really nice platform pedals on Amazon with spd clips on 1 side.

I bought this bike for the frame, mostly, so for that It did it's job. I replaced the tires and tubes (Vittoria hybrid road tires, 700x28c pictured), but kept the rims. I replaced the tektro brake levers with TT break levers from Soma. I replaced their handle bars with a T2 wing bullhead handle bar, 44cm width, very nice.... I've kept the seat for now, but it's not great and I'll replace it eventually. Also, I've seen plenty of complaints about the BB breaking,so I'm gearing up to replace that as well.

That said, I'm happy with my purchase. All in all, I got what I wanted for about $600, which is a few hundred less than the starter Throne or CYBORG, which I would still have had to modify.

Great bike for the price…one thing to improve.

6kU needs to checkout Guardian bikes directions on assembly, Guardians booklet and video instructions are a good model for any bike company to follow. 6KU instructions are for several bikes and need to be more model specific.
