Re: ebike laws with trike build

i was asking about the ebike laws. in the united states the law sais 750 watts and i have seen some youtube videos and google searches say that the more power can allow them to go faster. as well as multiple motors adding up to the total watts. so i was asking what triggers a suspicion of illegal eb...

Re: ebike laws with trike build

i would be using a https://www.ebikes.ca/shop/electric-bicycle-parts/stokemonkey-parts/sm-bracket.html to mount one hub for regen then i would use the cyclone motor for the power and i have the smaller bionyx motor i would mount in place of the coaster brake hub for the speed. what makes you think d...

Re: ebike laws with trike build

i also forgot to mention that the smaller wheels would give more power for on hills if you notice modern electric wheel chair scooters have very small wheels witch allow them to go up hills easier i think the stability issue is about ratios older trikes have very narrow wheelbase and are high and sh...

Re: ebike laws with trike build

instead of shifting i would use 2 separate mid drive chain drive motors fixed to 1 speed and it would set up a escher impossible staircase where trying to run both motors they would fight each other. also wiring up controllers to 1 throttle through a relay to ensure only 1 motor can run at the same ...

ebike laws with trike build

i am considering building a trike using a bike trike conversion kit like https://www.bicycledesigner.com/trike-parts/hollow-hub-trike-conversion-kit.html this will solve many problems. 1. broken kickstands as the 3rd wheel will act as a kickstand 2. stability i will be building it as a lowrider and ...

trouble sourcing 12s bms/balancer

i have a 12s chevy volt battery i am using and i looked on ebay and the only 12s bms that would work is $200+ in price. the cheaper ones for ebikes come in 1, 2, 3, 4, 5, 6, 8, 10 13, 14 and 15 s i was wondering the bms modules like the ones used by hoverboards can the last cells be omitted so it wi...

you say illegal how would the police even know if you are using it above the legal power?

i doubt that the police is trained on dyno'ing ebikes if they can dyno anything at all.

if you mean by too big in that it refuses to upload as it exceeds the board limits there is always tinypic or your isp's provided space or if your isp allows servers on residential account you can host from your own connection.

Re: charging chevy volt/spark batteries.

modern hobby chargers are smart enough to detect a battery connected. i think it may be that the internal resistance of the individual cells or s is lower than that of a normal lipo cell so maybe individually it cant do much but when you add up the cells there is enough resistance to make the chargi...

Re: charging chevy volt/spark batteries.

As far as I know, the Volt batteries are Li-ion, so charge to 4.2v per cell. what i find odd is why if i charge each cell as 1s at a time the charger does not taper down the charge and stop once it reaches 4.2 volts. i suspect maybe the volt cells are so proprietary that they use a custom chemistry...

Re: charging chevy volt/spark batteries.

another thing


you do realize that a chevy volt/spark battery module is 40 to 50 amp our rated and charging a 50 amp hour battery with a $10 charger that is probably no more that 3 amps will take 16 hours or more to charge?

that is why i was asking about the chemistry.

you can get one for as little a $10 !

does the $10 charger have balance connections and able to charge at 1000+ watts and be able to charge variable amount of cells and have a display like hobby chargers do?
