Gear indicator is complete. Pic Heavy and Video!

[Yev]

So my electrical engineering buddy and I built a gear indicator..
Here are some pics and a video:

[smaeda]

thats some cool stuff right there. Is that duct tape on the electrical wires?

Slap on some potting, and you're off to market.

Yeah, we put that on there for abrasion-proofing.. However, in the visible areas we used a different method:

It is more appealing to the eye. 

Slap on some potting, and you're off to market. 

Hahaha.. What's potting?
We are considering making some of these upon order from people.
So far we are testing these bad boys... They are waterproof, and can stand up to 110 mph (indicated) highway speeds. My friend has one running full time at his madman laboratory... so far so good.

Nicely done!

What's the LED on the left of the 7-segment LED for? 

[Yev]

It is something my friend added to verify that the circuit works.. (For example if something goes wrong with the 7 segment display the light will still be lit letting us know that the problem is with the 7 segment display.

If you do decide to make them I'd definitely be interested

[HPI_Freak]

me too! just make sure a very detailed instalation manual is included for dummies like me XD

[Worm]

Definitely interested! What are you thinking of charging for them?

I don't get it.

I understand the usefulness of a gear indicator for the first month of riding but eventually a rider should be able to look down and compare the speedometer and tachometer readings to make a fairly accurate decision as to what gear they are in.

I have a normal geared bike. At 65 mph the speedometer needle is basically pointing straight up...If the tach needle is advanced past the 6500 rpm mark I'm in 5th or 4th...If is less that 6500 rpm I'm in 6th.

Just listening will communicate which gear the bike is in as well.

Do most riders need a gear indicator after they have been riding awhile? (Say...3,000 miles or more)

It's just a nice feature to have. Yes, I have been riding for 3 years and can tell you what gear I am in by my RPM and speed.. but I like looking down for a split second and seeing it right there.

We might be doing these for order. But we still need to figure out cost and such. I would need to know who is definitely purchasing one and know that they are not going to bail once we invest our money into parts and labor.

I'm in if price is right.

[Worm]

What's not to get? It's about the bling!!!! 

[drduimstra]

so. . . . . . how much is it?

[black and silver twin]

Why will it only work for 110 mph? what would happen if that speed is exceeded?

[Bluehaze]

Trust me bro.. you will never ever know with your GS.

[plewis51]

Wow great feature. Count me in on one if you decide to market.

[O.C.D.]

Downhill with a tailwind you might, lol.

Great job on the indicator!  If I had stock anything I would snag one of these for the cool factor.

I have taken mine to 125mph indicated (redline in 6th with 15t sprocket) many times.

on flat road, dont know about tail wind though. I have done it enough times to rule out wind.

[Bluehaze]

nice.. thats an awesome feeling getting that on a GS i am sure.  You must be mechanically inclined.. for most of us its just a dream.


I think this is a great idea since this can be a "begginers bikes".   It takes out the stress of trying to figure out what gear you are in and more on riding.  Then once you get used to riding, you will also get used to hearing the gear/rev.  Its a win win situation. I hope the OP does sell this in a manner that would make it worth while to buy.
