Has anyone build an ebike out of a battery powered chainsaw? I've come across a battery powered pole chainsaw for free and was thinking of making a DIY ebike since I don't have the funds to build a proper ebike Does anyone think this would work?
It could be done and probably has been done but it might not be too effective. The biggest expense in an ebike build is the battery. Have a look around to see if you can recycle the cells out of second hand battery powered hand tools and put them all together to create a larger battery pack. It takes a lot of time and you need some knowledge and soldering skills but it can be an option for building a battery with limited funds.
How many Ah's is the Chainsaw battery? I've seen an electronic weed eater which was 2Ah and 48Volts which works out to about 96 Watts. Electric bicycle motors are usually around 250 Watts at the minimum. It might work but you won't get very far on a small battery pack of that size.
