Re: Info on stripping a DNP Epoch freewheel

At least a few years ago, the Shimano ones were selling in the hundreds of dollars... no thanks I never heard that. But foolishness being what it is, I'm not particularly surprised. The only reason 11t and 10t sprockets work on pedal bikes is because they're used so infrequently. On an e-bike, they...

Re: 19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tires)

I hope to get the speed upto around 80 kmh and/or increase the range. It still felt pretty stable, which was never the case with bicycle wheels, even at 70 kmh. I've ridden my own motorcycle at around 240 kph before. I don't own one anymore because motorcycles kinda suck compared to bicycles. Feebl...

Re: Info on stripping a DNP Epoch freewheel

[ One of the reasons I recommend against DNP freewheels is that the sprocket teeth are poorly formed and made from more wear-prone metal than Shimano or the better grades of SunRace freewheels. Except for those of us that need an 11 T sm.gear on a freewheel, there is no other choice. Not true. http...

Re: Info on stripping a DNP Epoch freewheel

I'm easier on freewheels and cassettes now than when I was young and fast. More diligent about keeping things lubed, equipped with more bikes to spread miles among, and just not that ambitious about riding hard. I would have jumped at the opportunity to use freewheels or cassettes with 11t high gear...

Step up. This isn't rocket science. You can do it, and the reward is a better and more useful practical understanding of your bike. You bought a kit, remember? Not a complete e-bike.

Re: Do rear hub conversion kits not some with rear sprockets?

So I got the hub motor and it did not come with sprockets. It has threads for the sprockets. A local bike shop told me that it's for a freewheel, the donor bike has a cartridge. What do I do? Just buy a freewheel from the bike shop? Yes. Should be like $15-18 retail. You don't need a tool to put it...

Re: Awkward torque arm installation - suggestions needed

Even with torque arms, you're very likely to break those fork tips off. The arms need to be strong and secure enough to hold your weight when that happens, or you'll get hurt. Front hub motors and telescopic forks are a bad combination, and not only for safety reasons. Motor thrust makes the forks b...

Re: Info on stripping a DNP Epoch freewheel

Seem to remember that there was no other option at the time. Think it was that there were no other cassettes available with an 11 tooth . There are abundant cassettes available with 11t high gear-- probably most of them. But what you have isn't a cassette. It's a freewheel. Your wheel can only take...

Re: E-Bike Registration

Note that by moving the chainring outwards, you may harm chainline enough that the inner sprockets won't be usable.

In that case, you can move the most valuable rear sprockets into the outer positions and lock the inner ones out with the derailleur limit screws.

Re: Magnum Metro: Freewheel Clanking!

I knew what the cassette is - I just didn't know that the freewheel mechanism is a separate part from it. That's what differentiates a cassette from a freewheel, and why it matters what you call it. They do the same job, but with no parts in common. So is the freewheel pressed into the cassette, or...

Re: Info on stripping a DNP Epoch freewheel

Chain wear and elongation is what wears sprockets and makes them skip. You can get typically 2 or 3 chains worth of life out of a cassette or freewheel, as long as you replace the chain before it's elongated past its operating limits. If you let it go too far, you'll reshape the sprocket teeth to th...

Re: Magnum Metro: Freewheel Clanking!

Shimano made the first successful cassette freehubs, and they're still the best in the business. The farther off in the off brands you go, the more likely the freehub body is to be unreliable junk. The bike has a Shimano Acera 8 speed derailleur drive. Are you saying that the cassette isn't provide...

Re: Magnum Metro: Freewheel Clanking!

When you say "integral to the hub" do you mean that the whole hubmotor assembly would have to be replaced? You later seem to imply that it can be replaced, with special tools. I'm confused... Cassette freehub bodies are part of the hub, and often specific to a single kind of hub. This is especially...
