ok thank you so much for all your help i only really have two questions left.

DC to DC converters http://www.electricmotorsport.com/store/ems_ev_parts_dc_dc_converters.php the first two have the 72 volt change so am i really gonna end up spending 200 dollars for lights or is there something better/ easier to do.

finally sprockets/chain. i dont get it at all ive looked at the equation things ive gotten that apparently more teeth makes for a better acceleration. is it necessary to change the sprocket and all or is it just an option?

ok im going to try and post everything i have questions on in this box :]

So first the BMS i would need 24 of the lithium batteries so it is a standard set up as you said depending on the price of that would probably change everything

now you kept saying about the cycles that it would depend on how harsh i was to them. now what would be considered harsh like would like "flooring it" hurt the batteries or is it just riding it too long that it gets past that recharge thresh hold?

finally battery charger are there any things to look for for wen i want to get one. I look at them and see so many things

those two are the ones i was looking at they are expensive so im assuming they are bulk chargers and they say stuff about 72 volts so i thought they would fit. if im missing something please make me aware because some have like 20A charger and im not exactly sure what that means amp? and then from there how to decide if thats what i need

o and you said the 72 volt e tek motor would be ok right? it would get the speed i wanted? just making sure

alright so how do you figure out how many batteries you need. you came up with numbers but was that a guess or a calculation. like how many lead batteries would i need in comparison to lithium?

another curious thought on my mind was are there any like solar panel abilities for the bike itself so while riding/sitting it will charge the batteries? or would that be too complicated?

Alright so I want to build an electric motorcycle but i am in the phase of pricing and playing with stuff like that. Frankly i am not a mechanic i fail at changing oil. i understand basics of stuff and have done research into this before but i dont remember much. Im thinking i have at minimum 3000 dollars to spend not a whole lot of money but its just a guess. I have looked at two different motors one is a 48 volt and ones a 72 volt i understand 72 volt is faster and that jazz but im looking for both economy and speed. I need at least a decent speed somewhere around 60 mph and a decent amount of travel time. I dont want to go around the block id like to be able to go out and do errands or go to work something along those lines. Also chargers with a DC connector is that saying like a normal plug like that can be put in a wall or what? that was my logic if im wrong inform me if not sweet. I would like to be criticized because i have no idea really what im doing i have done minimal research. I have done most of the research before. i know i need a motor and controller and dc to dc converter batteries are where i get lost most of the time cuz i dont get the Ah thing at all. there are some kits put together by electricmotorsports.com which is cool and where i was basing a lot of things off of. I was thinking the regen braking system because regen braking helps recharge the battery... correct? i thought that was a economical idea and helpful. so here are a few links of random things i was thinking. I also dont have a vehicle in mind obviously a motorcycle but kind and stuff are negotiable if you have any ideas about where to look ive seached craigslist and ebay but neither of those really worked i was thinking of a local junk yard but idk how well that would work nor do i know if they would have anything like a full bike they have full cars so i figure a full bike wouldnt be such a farfetched thing. I also dont understand sprocket stuff? like size and things i got an excel thing that did the equation for me but i didnt get how to match the info in the chart to stuff on the internet so any help with that would be great.

here are some links i was looking at mostly from the same website:

http://www.electricmotorsport.com/store/ems_ev_parts_motors_etek-r.php

and then the chargers and batteries all link from there not hard to navigate pretty much everything but my bike research has been from here. What do you think?? thank you for any help.
