100 W
My EEB frame started out as a regular 1000w 30mph bike...
The most I could do is 72v 1500w (more like 2500w @ 72v40a) getting me ~41mph and a motor that gets barely too hot after a heavy throttle session, even with holes drilled in the hub.
This only left me wanting more... more power... an upgrede here and there and then this happened...
In it's natural state... plugged into one of many many countless available power outlets found around NYC
I may have unintentionally gone the complete opposite direction of a stealthy look... whoops..
= 2006 YZ85 Seat and Body kit, fabricated to fit the EEB (many many zipties for the body kit)
= QS205 in 19" rim - Shinko 244 tire
= Sabvoton svmc72080 controller programmed @ 70a continuous
= Front 203mm + BB7
= Rear 203mm + formula Italy hydraulic
= 72v24ah 18650 battery
= 84v 1000w meanwell/laptop psu charger 84v13a
= Pops wheelies like no ones business and currently tops out at ~50mph
There's 12 36v4ah bricks, 2s6p. A single brick can do up to 20a but expect some voltage sag. 6 in parallel means 120a capable. On a full charge, the battery sags to 78-74~ volts when pulling 70 amps. I turned it down from 80 amps just to make it a tad easier on the battery, So a little more than 5000w fresh off the charge. Pretty good for only 24ah of "abused" 18650's ("abused" as in charging to 84.5v-85v every single recharge and running them at full potential every ride, frequently demanding 10-15amps per cell, for the past few months).
I could fit more batteries in the frame, but this thing is already really heavy, and I have to carry it up 4 flights of stairs, usually atleast twice a day.
So instead, I opportunity charge every chance I get . Finally got around to mounting the charger port inside for easy external access. Before i had to undo the two bottom screws to get to the charging port, now its just plug the charger into the wall, then plug the charger into the bike.
With 1000w continuous charger even 10-15 minutes gives a great recovery in range. Also, with a power meter on the bike and on the charger, I can see how many watt hours ive drawn from the pack during the ride, and also how many I put back into in recharging allowing me to know exactly where my battery is capacity wise. Range anxiety doesn't exist to me. Now that i think about it, i never really tested it's range on a single charge either ...
More pics to come...
