Hi There Nice project, maybe you can post some actual Pics of the scooter and any parts you already have ? I’m no expert but I upgraded a curie Ezip 750 and also a 500 3 or 4 years ago and had a lot of fun with them. Now I’m riding a electric skateboard (I’m a 37 year old =) ) I wired 8 packs...

Yes I know I can expect lower rpm with the xyd-14 motor, but I can easily go from the current 85 tooth rear sprocket to a 55 tooth. Could also replace the 11 tooth in the motor for a 15 tooth but that will be too much. It will run cooler at 1500w, and is a direct bolt on replacement, same bolt...

I overvolted an ezip 750 with a lower power rated motor to 48v with a 30 amp controller. 12s 20ah lipo It does 33 mph and also goes well uphill. It run reliably everyday for 2 months. Now something went south I suspect the motor but haven't open it up yet, still runs but at lower power...

I've been running a curie Ezip-750 motor (rated 24v 28amp) with 12s lipo charged to ~49 volts, and a 30 amp controller. It works great and I've been using it for commute every day for about 2 months. It does 33 mph on a flat with decent acceleration with me standing and also goes uphill...

nice man. I got a curie ezip 750 scooter. I replaced the controller for a cheap chinese ebay controller (20 bucks shipped) 48v 30 amps (DC brushed). Replaced the lead acid batteries for lipo. It fits 8 packs of 6s 5ah turnigy lipo, at 12s 20ah. replaced the throttle too with one with display...

I wonder why they don't mention at all the possibility of using this technology in vehicles. Cars, motorcycles, ebikes etc. Maybe even airplanes.

I received this news today: http://news.harvard.edu/gazette/story/2014/01/renewable-energy-breakthrough/?utm_source=SilverpopMailing&utm_medium=email&utm_campaign=01.10%2520%281%29 This is the original scientific publication published yesterday in the journal Nature ...

Looking good !! Good job on that battery pack.

It should be a fun bike for sure even with the big tires =). The roads around Boston are pretty rough, better have some meat in the wheels =). The bike also has no rear suspension. I just got a good deal on a set of Marzocchi Bomber dual triple clamp forks for the front. Should be nice and...

Thanks a lot for the advice ! I traded in the new 18 FET controller for a new 24 FET 4115 controller (thanks Lyen). Will parallel the pack for more amps and lower voltage. My packs are all 6S so could go 18S or 24S. I'm not sure how many amps people get out of the 24 FET safely. I asked...

Thanks zoombies and madin for the advice !. I'm glad I posted here before putting anything together. I'll try to get a 24 FET controller then. I liked the smaller size of the 18 FET but whatever. I still wonder about something though. At 125V , even if you don't supply enough amps for...

Thanks for the comment ! I'll definitely make sure everything is solid and stable. The europa has a very sturdy steel frame, more moped like than bicycle. The rear dropouts are 145mm so the cromotor slides right in like it was made for it. They just cheaped out in the forks. The thing is...

Hi Guys, I'm new around here. I got in the sport recently after acquiring a used ultramotor europa bike. I used it stock for a few months. Now is time to give it some real power :D :D :D :twisted: :twisted: Will post updates, and any recommendations are more than welcome ! So far I...
