Hi All,
I have a slightly more than half baked idea to make a “last mile “ electric transport option for myself.. Essentially inspired by the 20 minute walk (all flat) that I am from the train station whenever my ebike is unwell !
Broadly the idea is a lightweight folding electric scooter that packs away intto a rucksack. The budget for the project is, to all intents and purposes, zero
So far I have
1) A old powerhog mini electric scooter with twist throttle designed to take up 80kg (motor is 100w or 120w brushed and 24v rated). Bought for a fiver at a carboot as the 2 x 12v SLA batteries were dead and chap lost the charger. It was sold as spares or repair, weighs a ton as apparently made out of pig iron with a very loooong deck
2) A 25.9v 3ah (7s) lion pack built out of 14 x 1500mah high drain Sony 18650 taken from a couple of dead Matika drills packs (given to me for free). Due to the terrible design of the drill packs one series dies prematurely killing the pack and the BMS shuts down irrevocably when 90% of the cells are in perfect condition. All cells tested and matched to within a few Mah.
3) The first and original 1990’s Micro scooter. Bought by me back then. Built to last, very light, ultra foldable. Importantly with a very short deck by modern standards. Only room for one foot and toe of the other. Important given size of fold I’m after
I remove the heavy old SLAs and hooked up the li-on pack last night –all works a treat ! Easily copes with my weight (11 stone). Runs at about 10 to 12mph
My current idea is to basically chop off the rear 8 inches of the powerhog (ie motor, wheel, belt, and other gubbins inside it’s steel housing) and then bolt it onto the rear of the 1990’s microscooter. This will lengthen it, provide the power but be nowhere near as heavy as the powerhog itself. I’m hoping it may also allow an extra fold. i.e the bolted on drive unit folds under the microscooter
The battery will be inside a small rucksack which attached to stem/handlebars when on the move. When stopped the scooter folds up and goes inside the same rucksack
I’ll take a few photos tonight to illustrate - it probably isn’t clear what I mean exactly without some measurements, weights and photos
I’m posting for interest but also for input and ideas from the knowledgeable folk on here
Cheers
Kirstin
