Bicycle Shifting Indicator
Bicycle Shifting Indicator
Robot that reads your pedal revolutions, and indicates whether you should upshift, downshift, or stay in gear – Your Life on Your Bike. Easier.
Mattia
This robot is used to make your life on your bike easier! Using a button sensor and modified cam design, the robot senses how many rotations your pedals make every 2 seconds. With this information, the robot either lights up red to downshift, yellow to stay in gear, or green to upshift. To make the light more visible, I added a clear tube filled with hot glue to scatter the light. All mechanical parts were designed in CAD and 3D printed.
This is so cool! Very professional-looking and functional. I love how it doubles as a safety light in the dark. I would totally order this product. 🙂
Mattia, this is so so cool! I’m curious about how you determined the thresholds for the different indicators. Is it based on your preference or a particular RPM? When you were riding, did you feel like the robot recommended shifting at the same time you started thinking “hey maybe I should shift”? I bet this could be really helpful for anyone learning to use gears for the first time!
Bicycles are such a timely topic! Its a really interesting tool for riding a bike. I’ve been talking with my kids about gears and knowing when they need to shift. This would be great to help them learn when to shift.
Comment from my 8 year old (Connor): That is really cool – I would just want the light on the handlebars.
Great questions! I tested and tested until I found the rpms I liked to shift up or shift down at, and implemented those into the code. Anyone could go into the code and decide how long the readings should be and the rpms they preferred!
really cool use of materials to get this to work! This also seems like a very practical and useful product!
I really like how you 3D printed parts for this project. It looks really cool.
This is really cool! I would buy this for my bike! Its also good for night use which is amazing! Great Job!
This is awsome! Such a useful tool from such a simple sensor. I’d buy it for my bike (maybe release the STLs 😉 )
Will definitely release the stls! @mtb_3d on thingiverse and instagram. Stay tuned!
very cool how you took the original robot apart and used 3D printing to impliment it, in a different form.
I was very amazed by this because it is very creative and original!
This is so cool! I like how it can be very helpful.
Dang this looks and acts really well. Would definitely consider buying this for my bike.
I like how you took apart the robot and used it in a very creative way and extremely practical way.
This is so outside of the box and extremely useful. Amazing job!
Love the 3d printing, maybe this could make for an assistive bike or even a self driving one?
My thoughts for improvement are exactly that! I would love for the bike to use it servos or motors to shift automatically!
Wow, awesome mechanical design here. I bet it would be helpful for an electrically assisted bike too!
This is so Awesome! I think it would be really cool to have the robot automatically shift your gears for you if you clicked a button.
I had the same idea for an improvement!
Super helpful in the real world! The clear tube and the design overall is really smart!
Really cool project that has real world application.
Great job!
Seems like you could use this setup to train athletes.
I like that you used the clear tube of hot glue to scatter the light– I really needed something like that for my project! The mechanics of this is also super impressive and complex!!
this is awesome! I love how you used hot glue to make the light more visible!
I like how you used the glue to scatter the light. Very cool.
This is super cool! I like the light aspect of it.
