Brazilian YouTuber from the channel 'Metal Projetos' developed an electric bicycle with a treadmill motor capable of reaching 24km/h. the inventor has already developed several other interesting vehicles.
Have you ever thought about transforming that treadmill that has been sitting in your house for years into something more interesting? That's what the Brazilian YouTuber on the channel Metal Projects, Schirleno Almeida, did, transforming his ordinary bicycle into a electric bike with treadmill motor. The project gained prominence on social media this week.
Youtuber explains how he developed the electric bike with an ergometric treadmill motor
Schirleno Almeida reports that he initially used an older, rusty wheel, with a 20-inch rim, as traction. After cleaning the material, he removed all the spokes from the rim to drill strategic holes. The smaller rim was attached to the electric bicycle wheel using pieces of rubber.
With the rear part almost finished, the subsequent challenge was to determine the ideal location to install the treadmill motor. To support the propeller, he welded two metal plates to the bike. The motor was then connected to the smaller rim via a belt, and a automotive pulley was added to increase the belt's contact area, enhancing the transmitted force.

Equipped with a 450W controller and a 36 volt battery, the electric bike with treadmill motor It worked in an exemplary manner, presenting excellent power. However, considering that the propellant supports higher voltages, Schirleno opted for a 45 volt battery. In a top speed test, it reached 24 km/h.
It is worth mentioning that this speed may be higher if the battery provides a higher voltage. On steeper climbs, you need to use the pedals, as the engine does not have enough strength to tackle them alone.
Other projects gain notoriety
In addition to this electric bicycle with a treadmill motor, the Youtuber has already developed several other models with different motors. Among them is the electric bike with makita motor saw marble. With the tire in the air, this version developed by Schirleno could reach more than 100 km/h. In this project, a car battery attached to the back of an electric bicycle was used.
However, as it does not have as much torque, in tests carried out on the track, the vehicle reached a topspeed of just 30 km/h, which is incredibly high compared to the electric bikes sold on the market. Among other innovative projects developed by the Youtuber are an electric baby stroller, a hybrid bicycle, an electric handcar, a bike powered by friction with a brush cutter and much more.
Reddit user develops bicycle powered by washing machine motor
A very creative engineer used parts from a washing machine to develop a Electric Bicycle modern based on a common model, which I already had 20 years ago. The unprecedented creation was posted on Reddit, a social network that works as a kind of forum, identifying itself as Jimminecraftguy. Electric models are currently in fashion, as they are strongly linked to sustainability and environmental preservation.
The user-developed electric bicycle has been nicknamed the The Spin Cycle, which translated into our language is something similar to Centrífuga Bike. To develop it, the inventor used a 1.100 W washing machine motor attached to the center of the bicycle frame.
After that, it was enough to pass the vehicle's chain through the propeller gear which, when activated, moves the chain, leveraging the rear wheel of the vehicle. According to Jim, his electric bike can reach up to 110 km/h, enough to make the rider break out in a cold sweat.
