Biking is an effective way to spend time outdoor whereas concurrently getting train and at the same time as a mode of environment friendly transportation. And in the previous few years because of the latest proliferation of e-bikes available on the market and the pandemic, there was an explosion within the variety of individuals wanting to make use of bikes regularly. Just a few individuals have gone a step additional and have taken it upon themselves to create gadgets that make this expertise safer, extra handy, or extra enjoyable. For this 12 months’s World Bicycle Day, let’s have a good time these makers and the way they had been capable of creatively embed Arduino merchandise into their designs for a greater biking expertise.

Computerized shifter

The aim of a transmission is to transform the rotation of the motor into torque for the wheels, with extra being wanted at decrease speeds for acceleration and fewer when cruising. Equally, most bikes even have gearing whereby the rider can downshift to stand up a hill or upshift to make bigger strides on a straightaway. Jan Oelbrandt’s Shift4Me undertaking eliminates the necessity to consciously take into consideration this because it makes use of a magnetic cadence sensor hooked up to an Arduino Nano which permits it to routinely shift up or down relying on how shortly the pedals are shifting. 

Bikelangelo water “graffiti” trailer

Much like how a persistence of imaginative and prescient (POV) show strikes quickly altering pixels by means of the air to supply the phantasm of a bigger picture, maker Sagarrabanana devised a towable bike trailer that sprays water on the bottom utilizing seven particular person jets which take the place of the pixels in a POV show. Managed by an Arduino Nano, the jets’ timing is decided by the bike’s pace with a view to exactly deposit even traces of water in a dot-matrix sample. Textual content from the person is inputted on a cell phone and despatched to the Nano through an HC-05 Bluetooth® module for printing. 

Biking place sensing

Bike computer systems are nice for accumulating detailed data on pace, cadence, energy output, elevation, and extra, however none can say whether or not the bike owner was sitting or standing for a time period. Because of this Fabio Antonini used an Arduino Nano 33 BLE Sense and Edge Impulse to develop such a tool. He began by gathering 20 minutes of him sitting on a airplane, sitting whereas going uphill, leaping on the pedals going uphill, and pushing on a flat dash, then after coaching, deployed it to the Nano. To be able to inform what’s being detected, the built-in RGB LED modifications coloration to inform the person. 

An uncommon two-wheel steering system

Prolific YouTuber and maker James Bruton is not any stranger to distinctive robots and autos, and his tackle the bicycle is not any completely different. In contrast to a conventional design that has a free entrance wheel and a locked rear wheel, this e-bike has a hub motor in each wheels that may flip independently because of a further pair of motors. When the rider turns the entrance wheel, an Arduino Uno reads the encoder worth and makes use of it to spin the rear wheel in keeping with certainly one of three modes: lock, mimic the entrance, and mirror the entrance. And though the ensuing creating isn’t too sensible, it’s an effective way to see what’s doable when pondering out of the field. 

Clever lock

Practically each bike lock in existence is operated by inserting a key right into a cylinder and turning it to launch the secured body and/or wheel from a publish. Whereas this strategy works, it additionally lacks a number of helpful options comparable to keyless entry, cellular connectivity, and site monitoring. The TapLock undertaking reinvents the lock by counting on both a collection of bodily faucets on the lock’s enclosure in a sure sample or a paired cellphone to unlock. Past this, the TapLock’s Arduino Nano 33 BLE Sense communicates with the cellular app to retailer the present location on a map and even remotely lock the bike. 

Compact flip indicators

In a automobile, signaling is as simple as pushing a fill up or down to point your intention of adjusting lanes or turning, however for bikes, this function falls to the rider having to maneuver their arm round. Tom Ouwerkerk’s resolution was to buld a really compact sign by combing two eight-LED NeoPixel strips and an Arduino Uno to behave because the sign. The strips sit on a gliding mechanism which strikes both left or proper because of a servo motor beneath, and it helps to make clear the meant path of journey even additional. 

ML-powered adjustable suspension

Increased-end, trendy vehicles are starting so as to add routinely adjustable suspension techniques to their drivetrains which assist to adapt the automobile to the present terrain, atmospheric situations, and the driving force’s consolation stage. Jallson Suryo was capable of create his personal because of an Arduino Nano 33 BLE Sense and a servo motor that turns the bike’s entrance suspension fork to extend or lower stiffness. Terrain recognition was completed by coaching an edge ML mannequin on IMU readings and utilizing them to differentiate between idle, clean, medium, tough, and dash situations. 

Connecting a stationary bike to a simulator

Bicycling simulators are an effective way to expertise races towards others, discover trails, or just get pleasure from a pleasing journey it doesn’t matter what the climate outdoors is. Zwift is one such software program, and two essential options are that your precise pedaling pace is matched in-game and the sport controls the pedaling issue. Gene’s Inexperienced Machine was capable of combine his bike with the system by connecting an Arduino Nano 33 IoT board to a DPS5020 cost controller for studying the present wattage and setting the goal resistance. All of this data is distributed and acquired by using the Nano’s capabilities. 

A online game controller

Much like the earlier undertaking, online game creator Jelle Vermandere wished to journey his bike indoors alongside a digital observe. However this time, he took it a step additional by not solely integrating his bike utilizing an Arduino Uno which determines the wheel pace through a magnetic reed change, however constructing the sport himself in Unity. He needed to assemble and animate fashions for himself, the bike, and the surroundings. After including an AI and rating system to the sport, he was capable of efficiently race throughout the digital surroundings on an actual bike. 

Responsive LED system

Motivated by the will for a extra superior lighting system whereas on her nighttime bike rides, Natasha (TechnoChic) determined to affix strips of NeoPixel LEDs throughout her bike that would react to music in real-time. The LEDs are managed by an Arduino Nano 33 IoT that’s, in flip, related to her boombox through a 3.5mm audio jack for studying the audio sign. Two extra Nano 33 IoT boards had been used for the wheels, together with extra NeoPixels and batteries for every. 

GPS tracker

Bicycle theft has been quickly growing during the last couple of years, which is why with the ability to get better a stolen bike has turn into important. Johan’s bike tracker undertaking incorporates an Arduino MKR GSM 1400 which reads movement knowledge from an IMU and makes use of it to find out if the bike has moved when it isn’t presupposed to. As soon as motion is detected, the board reads GPS knowledge from a MKR GPS Protect and sends it over an LTE knowledge connection in real-time in order that the bike may be discovered. 

Built-in security options

Nearly all of mountain bikes lack helpful security options comparable to built-in lights, flip indicators, and pace monitoring, which is why Collin Wentzien launched into his “(not so) electrical bike” undertaking. He constructed a collection of options, together with automated brake/flip lights, a headlight, and an digital horn with the purpose of bettering security. Moreover, his bike additionally bought a motorcycle pc improve which incorporates an Arduino Mega, GPS module, and twin screens for displaying related telemetry knowledge. 

Speedometer show

After shedding the show unit for her bike pc, Element14 Presents host Katie wished to exchange it with a DIY model that tracked the present pace through GPS as an alternative of wheel rotations. An Arduino Nano 33 IoT board dealt with communication between the small 1.3” LCD display and certainly one of Quectel’s L80 small form-factor GPS modules. On every loop of this system, the time, pace, and distance are all proven on the display because of the 4D Methods genieArduino show library. 

BLE-enabled biking pc

This final DIY bicycle pc was made by YouTuber cubicpixelDE, and it integrates an Arduino Nano 33 BLE Sense together with a myriad of bicycle sensors and a coronary heart fee sensor over BLE to show helpful knowledge to the rider. The complete system combines a 1.8” coloration TFT display and the Nano 33 BLE Sense right into a single, compact unit which inserts alongside the handlebar and reads out knowledge to a cellular app wirelessly.
