To beat that Castle would need to bring something new to the table (some are far-off)
-better programmability
-more power/reliability
-smaller size
-100% waterproof
-attractive display for handlebars
-data logging
-adjustable dc voltage (run 36v off 72v battery with flip of switch)
-gps
-temperature monitoring/cutoff (controller and motor)
-on-the-fly current/speed adjustment
-built in switch/pre-charge circuit
-voltage sources for lights, etc.
-vivid flames and raunchy green monsters

you forgot updatable as programming improves

I would support a castle E-bike complete ready to bolt-on kit.

Metallover pretty much listed everything Castle would need to accomplish to be competitive in the current market. The Chinese own this market as they are the number one consumer of Ebikes by a large margin.

My cheap Ebay kit, is waterproof, has overvoltage protection, voltage cutoff. For $239 shipped, I got a hub motor with tire and wheel, controller, brakes with switches, a bag, rear rack and throttle. I'm 190lbs and on 14s lipo, go 27mph(last Saturday speed). With headwind 23mph. Castle will have a winner, if they can beat that performance and pricetag.

Castle ESC's have to work with hub motors that are around 5kV and up. The ESC's also have to be able to endure longer peak power.


That Brammo monster does make you wonder why there are 12K ebikes around.

Its been done with hobbyking electronics.

Castle has what it needs to start in the ebike market with a 36v controller. If they would up the components of the HV line to 65v we could have a solid 12s controller. The only thing lacking is TIME!
