Hi guys!
I've been checking out the forum for a while now, a lot of interesting stuff, very helpful as well. Unfortunately, my budget does not allow me for converting my beloved Ford Focus (the Euro version, not that small American stuff ).
Prices of petrol are rocketing sky high in UK, they seem to be the most expensive in EU at least, not even trying to compare them to prices of so called 'gas' in States. Anyway, lately, I use my car very rarely, on bad weather days (yes, I was lucky to have only few of those for last few months). Mainly for going to work... In a car, it takes me 4 minutes on average to get to my workplace... On the other hand, if I walk that distance, it takes me (even though I walk fast and take few shortcuts) 27 minutes on average. I was considering bicycle, but then there's few annoying hills on the way, and I can't really ride it on muddy footpaths where I normally walk. I was considering motorbike of some sort, but it would cost me a lot just to get the licence and then to insure it...
I checked few electric bicycles that are available on the market, but the prices are out of my budget anyway (at least 500 for basic poo). Then I found some electric motors on eBay for something like 40 quid... But then whole kits cost like 300 quid... So guys, does anyone know what would I need except the motor and batteries to make that sort of conversion? I'm not worrying about frame structure, that problem can be solved cheaply with the tools I have available. I'm more of mechanical skill person than electric, so I have no clue what I'm on about I mean, do I really need a controller just for a damn bicycle? I want to keep it lightweight, as I live on first floor, and the distance is max 5miles round trip... Any advice would be appreciated!!!
