Re: Type of wire for phase wires

Phase wires are silver thinned copper, multi strand but not so many, so they are pretty stiff. PVC Halar insulated, very thin and robust insulation to make the max copper size fitting into the axle channel and prevent friction wear. After the phase wires are out of the motor, I like using a larger g...

Re: Type of wire for phase wires

After trying many, I have found that no wire does beat those that are stock on big hubs. If you want to upgrade, buy the wires from a bigger hub than yours. If you repair, use the stock wires. When you scrap a hub, keep the wires. The closest match that I have found on the local market, is HALAR ins...

Re: Specialized Levo vs BBSHD

Specialized are very expansive of course. Part of the cost is into exceptional after sale service and warranty, and a fair part of it is into continuous development. They don’t really make profit with their top of the line bikes, because it is too small a market. Their profits are from large series,...

Re: Specialized Levo vs BBSHD

Last year, I have tried the Levo carbon top of the line S-Work, in my usual mountain trails. I ride these trails all the summer with 25kw of power, so no comparison of price, power or speed here, only riding and handling feel. I my life I have ridden many pro DH racing bikes that were not as good ri...

Re: Specialized Levo vs BBSHD

The Levo series are among the best bicycle feel that there is right now to ride mountain trails.

Easy to build better performance for much cheaper, but almost impossible to build a better ride, mtb wise.

There is a Radpower dealer here nearby. He has a cargo bike equipped for service on the road, the only one that I have seen around. It is a fact that new ebike users, and most of those who are buying ebikes in the commerce, are not able to service their bike by themselves. And, many ebike riders don...

Re: Zoom DH1100 fork

Inverted forks are not very popular anyway. I prefer using common racing forks because they are easy to tune, and can be serviced quickly.

Re: Zoom DH1100 fork

This is a very cheap ´DH’ fork. I’d say it is OK if you plan to ride the streets, but for mountain trails you’d be better with a used DH fork that has complete tuning options. A good used DH fork can be found for twice the cost of a new Zoom fork.

Re: Buying Advice - Old High End or New Low End

I wouldn't buy an old ebike.
It is definitely an advantage to buy an old, top of the line bicycle, and build on it. Yet it is not the same for ebikes, because ebike components and batteries had improved a lot and older ebike frames are mostly Chinese heavy old tech.

Re: What lock and how many do you buy?

You need to set traps to catch bike thieves, and after you caught a few in your neighborhood, you should be able to keep a bike safe for a while. Are you suggesting involved traps with "bait" bikes (like "bait" cars) or do you have something less elaborate in mind? Setting thieves traps is another ...

Re: Ebike

Well, if it is running fine backwards, half the job of finding the proper combo is done. Swap any two (only two) of the big phase wires, then swap one of the 3 other possible combinations of the (blue, green, yellow) hall wires. One of them will give you a perfect forward motion.
