Thats the chain I am using on mine and is better quality than the original chain on my Apollo Evade and also better than the "Tour de France" chain bought off ebay.
At less than £4 a time I am happy to replace my chain every 3 months and at the end of the day this will also prevent excess wear to the sprockets which,after all, are a lot more expensive.
I wanted to have a try.

I installed and added a bit of purple extreme.

But on high load (when bike starts) the chain slips on the rear freewheel........ it didn't on my previous chain.... :(


3 possibilities:
1. The chain is not strong enough to deal with 750W and slip
2. Adding purple extreme create slippery
3. The freewheel is worned out and need to be replaced. But it was working fine with previous chain :(

What should I do? :(

Check the freewheel for wear, if it has wear the old chain was probably worn the same amount so still worked ok, new chain nolonger meshes correctly.
I have not had the issue personally, but it seems fairly common and there has been a couple of similar threads recently here.
1 and 2 are very unlikely.

I tried to remove the rear freewheel turning anti clockwise with wrench...

It didn't move. Then tried again with hammer and wrench and still in place. Any idea how to sort that out?
Thx

Does it also protect against rain? And does the chain needs to be cleaned before lubricating? If so, anything you'd recommend?
I normally clean my chain before lube with a chain scrubber like this one.

I also had the problem of a new chain slipping on worn cassette and have ended up keeping the worn chain and cogs on since they all still work together for now.

If you don't have the tool maybe take your wheel to a local bike shop they will have it changed in minutes. Saves you buying the tool.

I've spent 1 hour trying to remove the freewheel and it didn't take out. I used big wrench + hammer then big wrench + leverage (all my body on the wrench and jumping on it) and it was still well fixed on it.

I'm thinking that maybe it's time for me to use cassette... at least I'd be able to remove it quickly. Does it worth changing it? And how is the maintenance with cassette and will it be cheaper over time? I'm expecting worn cassette quickly too

I bought a freewheel removal tool off ebay for £2 delivered. It helps if you grip the tool in a vice if you have one, and turn the wheel. Freewheels get tight. Failing that LBS. If you take just the wheel, they will probably do it for nowt if you buy a new freewheel.

I may pop to a shop but I never had good experience with them. And its also super expensive, i may rather buy a new wheel instead

A steel housing screwed into an aluminium hub, using a fine thread, and tightened by repeated application of the cyclists weight on the pedals, together with torque from a powerful electric motor, in wet and possiblly salty conditions...
Probably seized up and the threads corroded beyond use anyway.
However, there is a trick you could try... Put your wheel, soaked in penetrating fluid, in the freezer as cold as it goes, leave until thoroughly frozen.
Then take it out , get it in position, and pour boiling water over the hub, but not the freewheel. Apply torque to the removal tool and pray it lets go! ;)
Next time use waterproof grease like 'Coppaslip' on the threads before assembly.
Likewise you can put new cogs on an old, good freewheel body from the same shmanufacturer, by using a chainwhip on the unscrewable locking cog (small one) and another in opposition on the next, fixed, splined cog. Put back the shims and spacers as found or cogs will not align with derailleur indexing.
Good luck, admire your "get on with it regardless" attitude.

I would just clean the cassette spline with some wirewool and wd40 and maybe lube the bearings etc too. I think I would get/use a cassette with the same number of speeds as the original freewheel had.

The method i have used for stuck free wheels is to put freewheel tool in , then holding tool in place put in bench vice tighten up then both hands on wheel and turn workes 9 out of 10 times , failing that i use a crack bar

For removing seized parts after leaving penetrating oil on for a while is to not yank the pressure on but put the pressure on slowly and on as much as you can and hold it there as long as you can, generally the seize kind of cracks/gives.

Clean the spline lightly with wirwool and oil, wipe off and apply a little brake grease( coppaslip).

Thanks all.

I've now changed to a new cassette and chain. It all almost work fine.

The front chain sometime fell off while riding. It happens most of the time when I change gears.

Would that be because the chain isn't properly tensioned?
Or maybe i need some front chain alignment guide?

Falls off the front cogs or rear cassette? If it's rear cassette then the derailleur stops need adjusting. Also count the number of links in the old chain and check the new chain has the same.

Is it falling off when in the lower gears?
Probably a guide is need as the BBSxx sits further out than normal causing a bit to much angle, if your original front deaileur can reach out far enough you coud just use that or any other chain guide.
