Pakistani Electric Bike (Recumbent Rear suspension)

Rear suspension is comfortable but acts as a sling-shot when passing through a large speed breaker, Dissing the upgrades to be applied. Video is specially for precious opinion of Professions and dedicated nice people on Endless-Sphere website.

Good effort. Have you finished a working electric bike.

@selfcoaching123

Thanks. The one shown in the video is fully functional, only that electric power break down compels me to use my gas powered dirt bike. see the video where I am riding it on my street where I live: KsVvAovou6Q

You could ebsorb the shock and not restrict the travel with prehaps wire coil and magnet soliniod suspention dampers and make electricity ?, but this will be time consuming to experiment and costly for magnets, also to heavy.

You would have to study many electronics princibles in physics and science.,

@coaxialgyro I thought about this which could be just like a coil inside a speaker but as you said It would be expensive and increase weight which is not desirable in Electric bikes. Moreover, the energy it will produce will be very little so, power to weight ratio of entire practice will be at the cost of so many things.

my guess is that only the spring works but there is no damping

@dajsinjo Thanks for your comment; Yes indeed you are right. It is Chinese brand and its true that only the spring works. I'm intending to use a motorcycle shock absorber would do fine alongwith this one already installed, as suggested by liveforphysics532.

very loooooooooooooong chain from the pedals to the rear wheel ! nice homebrew bike.

You're awesome Naeem. :)

An automotive shock absorber, or motorcycle shock absorber functions to delay the rate that the spring is able to expand again after compression, which stops the harsh bounce back effect you're feeling after bumps. It can be mounted anywhere between the rear suspension swing-arm and any point on the frame.

Very interesting that it stores energy from speed bumps. Much like a kangaroo tail, its returning energy lost, but sadly makes bicycle unsteady. Hopefully your mods will redirect the energy else many need try different springs. There is video of recumbent on youtube going downhill against normal upright bicycles (not pedaling) and recumbent just breezes past them. Hopefully your recumbent design will reduce wind resistance which should increase range of batteries.
