So, I’ve used the single speed a few times now to go down to work and back. Good lord, its hard work on hills with just a single 16 tooth cog!

There have been a few issues, the main one, was the left hand crank unmounted its self and went a little rounded out. The bolt had worked loose and came away, causing the crank to come off the bottom bracket spindle. Because of the cheap Chinese metal it had rounded out part of the mount in the crank.
A good battering with a hammer, and it was back on, the bolt torqued well over spec to hold it in. I’m not sure if getting it off will be an issue, but brute force may see it shifted if the crank puller has any issues.
Then, a day later, I thought I saw a little play in the handle bars, so I stopped and had a look, yup, play. The stem face plate bolts had loosened off the stem, so tightened them back up too.
So, I’ve ordered a new Crank set from SantaFixie to replace the damaged one, and I also have a full set of brakes from Tektro to fit too. These will replace the downright dangerous ones supplied as stock on the bike. The stock ones are awful in the dry, and downright dangerous in the wet. The calipers have way to much flex in the arms to apply any decent pressure on the rims, and the rear isn’t even able to contact the brake track. I’m not sure of the makes of the pads, but I am assuming they too are penny purchases. So, the Tektro brakes, while not a top end brake set, will be noticeable difference to the braking I hope. I might at some point replace the brake levers too, but that’s not an urgent need.
Riding the bike is nice enough though, the bike is easy enough to ride once its up to speed, and comfortable. Its a good flat bike, but because of my fitness issues, I do really miss the gears on the hills. Still, it makes me appreciate my proper road bike all the more. I can live with the front mudguard rubbing slightly, I can live with the weight of the bike. The issues I’ve had with the bike can be overcome with a little work and part replacements. So all in all its not a bad bike, just built to a cost point. I think I’m going to liberal with the loctite on this bike in future..
