Gear Range Difference between 7 Speed and Internal 3 Speed Bikes

Hey everybody, how's it going? Peter Kaltreider with Sixthreezero. Today we're going to talk about the difference in gear range between a seven-speed versus an internal three-speed. Stay tuned.

What is the difference in gear range between a three-speed internal bike and a seven-speed with a derailleur? We get this question quite often. And so, what we're talking about with gear range is what's the difference between the easiest gear and the fastest gear, your slow gear and your high gear, low gear and high gear?

So anyway, we have a different video on how to calculate that, and the gear range is expressed in a percentage and they can be all over the place depending on what kind of use you're doing. But for a recreational rider and for an e-bike rider, really you're going to just need about 200%, which is exactly what our seven speeds have. It has a 200% range, meaning that the high gear is going to be basically twice as fast as the low gear.

It's kind of a layman's way of putting it. Anyway, you'll find that it's plenty of range for any kind of paved riding that you want to do. If you're a mountain biker and you have an E-Mountain Bike, different story, you're going to be doing lots of tough terrains, steeper and all that, you're going to want a bigger gear range. But for the recreational rider who's riding on a bike like this on any paved road, the 200% range is going to be great.

Now, the three-speed doesn't have quite the range of the seven-speed as you would imagine. However, it's actually pretty close. Surprisingly, whereas the seven-speed that we have here is a 200% range, the internal three-speed is going to be about 180%. So, they're actually pretty close. The seven-speed does have a wider range.

It has really nice, easy gear. It's a large 28 tooth here in the back. The larger in the back, the easier it gets. And the 28 tooth is that's a really easy ratio. So, we have a 44 in the front and a 28 in the back that gives you a one and a half ratio, which is a pretty, pretty easy gear. With an e-bike assist, it's really all you would ever need on any paved road that you would encounter. So, that's the difference.

There's not a huge difference. The seven speeds do cost less because actually, the internal three speeds cost more to manufacture actually, but you get a little bit of advance with the range on your seven-speed, three speeds require a little bit less maintenance than the seven-speed. So anyway, a little bit off-topic there, but that's it for the difference in gear range for seven-speed versus three-speed internal.

All right, thanks for watching. I really hope that was helpful.
