I take an ordinary wheelbarrow and bolt on a motor from a wheelchair couple it to a home made Lithium ion battery pack and well the results speak for itself.
Wheelbarrows are such a pain in that they need you to put in all the effort.
My aim with this project is to produce the best budget electric wheelbarrow that costs less than £200 ($275). I use second hand Lithium ion cells from old discarded laptop batteries as my power source and a second hand wheelchair motor to power it all with.
