How to cheaply increase the top speed of an electric bicycle
I'm into gaming, and know some people that do custom add-ons (all I've done is paint my Tzolk'n board). But as others have said, where do you place the numbers? What do you do with the robber? If you had kept a dedicated circle on each tile(especially the mountain tile) then that would make it workable.
Well yes, I'd spend that money buying better batteries instead of testing dodgy ones too. But if you work in electrical engineering, and already have access to that equipment.....Anyway, just letting you know it wasn't test method or circuit calculations that was giving you that result - it really is the batteries at fault.
I've used profession load banks (cost $1000+) to measure battery capacity of the Chinese ebay purchases and got the same result. They outright lie about the capacity, and don't seem to care about the repercussions (lets face it, what can you do?). The only solution I've found is to pay retail prices at a local store where you can take it back if its not up to scratch.
Thanks for the praise. The highest speed I ever got was 45km/h (on a slightly downhill straight run) with a 55 volt input. If you are prepared to stress the components of your controller and motor, you could increase it up to 80 volts(with this DC/DC converter) with a top speed I would estimate over 60km/h. But this would be unsafe for the electronics, your health, and the safety of others on the road.As for the laws in my country, somehow full sized electric mopeds, with headlights and indicators, are legally sold. These clearly break the design rules that limit electric bike maximum power to 500W, so it doesnt seem like the laws on the books are being applied any more.
This is truly an impressive achievement considering what you started up with. Not sure what was the top speed you reached with that dc/dc converter but I think that you might have still been very close to what the law classifies as an electric assisted bike. if I have a choice between a bike that does not move, or hardly so or bordering on breaking the I would choose the latter. You basically turned a piece of junk into a usable electric bike. Kudos to you!
You inspired me to look up the laws where I live. By doing this I break them too. I'd say its borderline to do any mods to any commercially sold products and still have it 'legal'.
Awesome job! Very well written ! Thanks for sharing! - NYCitySlicker
You should add a disclaimer that in certain countries (e.g. Germany) you will brake the law doing that. - ThomasK19
