Do I use the gears off my old rear wheel to maintain the 18 speed?

In answer to your question it is yes. We kept our old 21 speeds by removing the old one off the wheel and putting it on the new wheel. You will have to purchase a special tool in order to do this or have a bicycle shop do it for you.

Th kit comes with a new sprocket. I mine has 6 gears. But, with the electric boost I find I don't need the bottom gears nearly as much as before.

You can use the newer version provided the gearing is the same. I used this Sora to replace a Shimano shifter from the 90s so I am sure it would be fine to upgrade an older version of Sora (again, provided you are using the same number of cogs on you front crank and rear cassette).

I put it on a cassette with 8 speeds worked fine but I don't remember how may teeth were on the gear and I no longer have it.

Yes, no problem to use your 8 speed cassette. it will fit right on. thanks, ben

i dont think it would. a 6 gear assembly may be narrower than a 7 gear one, this wheel may be too wide for a six speed bike rear fork.

No problem your bike will not be changed unless the rear skewer doesn't work which is unlikely and there is nothing to changing that. There is a skewer in the box if you need it. I run an older rear wheel that has a very worn tire which works very well.

7-8 speed refers to the rear gears on the cassette. That's what really matters here. If the back has 7 or 8 gears, it will work. They come up with 18/21/24 by multiplying the number of front gears (usually 3) by the number of back gears. 3 x 7 = 21 or 3 x 8 = 24. Frankly, I don't know how they come up with 18, because that would be a 6 speed rear.

Hi there. It is the front rim so there is not a gear. You'll need the rear rim if you're looking for the gears for the derailer

I put that crankset on my hybrid which was set up for a 48. Using a 48 on your bike will require moving your front derailler up some and it is possible that your rear derailler won't have the capacity ( length of the derailler arm) for the larger gear. However it possible to change the ring gears on most crank sets and you could use your old 42 gear. I'm not sure about this but 8 speed set ups might not have compatible gear teeth with 9 speed crank sets.

I've done it before without issues. Use a 9 speed chain to reduce the risk of rubbing between chain rings.

Yes ,as long as you still have the motor inside the trunk! take the exterior retainer nut off .Turn the key on and expel the old base and plastic geared track, Feed the new one in ( teeth to the rear) turn key off to pull the new gear track in. May take a couple times to seat perfectly but should !Replace exterior retainer nut !

Should be no problem, since they are simple friction shifters with no stops. Both shifters are basically exactly the same. I am currently using them on a 7 speed rear, changed from a 5 with no issues.

That should work out fine. Just be sure to get the hub with the coaster (back pedal) brake. I assume that you are getting a complete wheel but if you are building a wheel you'll need new spokes since the hub diameter of the 8 speed is much larger than the 3 speed.

yes, just have the old 7 speed, i got this one for this wheel Shimano Tourney 7Spd 14-28T Freewheeland it should work perfectly as it has for me

I don't think so- it there a quick release on the rear wheel? You would have to be able to remove the skewer from the rear wheel to replace with the one included. I had an old 10 speed with a quick release and we still had to modifiy with washers because it was not the standard size for newer wheels.

Yes.. its the same wheel. You only have to move the gear plate that screws on the back to the new rear wheels. These were a perfect fit!

That depends on the cog you use. the hub's first gear is normal (as in a fixed speed, no modifications) while the second gear is around 30% higher (harder to pedal). So if you are confortable with a single speed that uses 44 teeth front, 18 t cog (as an example), if you replace the hub with this one, and keep everything the same (44,18) it just wont we comfortable, because first would be the same as you had, and second would be too much. What you would do in this example is replace the cog (about 5 us here in amazon) for a bigger one, say 22 teeth. Then the first speed will be easier ( a help to get going) and the second will be similar to what you had before (somewhat harder, but since you will have speed by that moment you can get away with it). I hope I managed to explain this, but the idea is that you have some control (using cogs, not hard to do but you may need help from your bike shop) over how the hub works. it will always shift between normal and 30% higher, but you can control somewhat how (low/medium/high, which is of course subjective) your normal ratio is, and it shifts to 30% harder to pedal. It really should be marketed as a 'start assistant' for a single speed IMO, because this is what it does, and its amazing at doing that..
