This bike is the Copperhead 1000W E-Cruiser manufactured by Soul Beach Cruisers in Tempe, AZ. For technical specifications refer to (soulbeachcruisersdotcom). They are much better informed than I am. Here is a partial list of the major components: Bafang BBSHD mid-drive electric motor Sturmey-Archer 3spd internal geared hub Cycle Analyst computer Hydraulic disc brakes 48v 13.5ah battery pack This bike is ideal for the big and/or tall rider. As to top speed, it will vary depending on terrain, wind, rider weight, etc. On flat terrain with little or no wind I can hit 27mph and I’m not a small guy. Questions about battery range are also unanswerable due to similar variables that determine top speed. The motor is rated to draw not more than 30 amps and the battery pack is rated at 13.5 aH. I won’t do the arithmetic for you; I assume you can handle that. One last thing, the ratings and specs come from the manufacturer. If they’re wrong, yell at them, not me.
