I looked these up at their website and the only ones listed there have BionX kits on them. The ones on Clymb have 250w front hubs and are most likely EPAC compliant. It is funny though that on the Clymb offering there the female cruiser offered in blue at least per the picture retains the BionX kit and is offered for 699.98 which would be a screaming deal because those kits list for about $1800

That aside for Portland a 250w 24v system will not get you much satisfaction. The Oregon wattage limit is 1000w and although limited to 20 mph it is all about how fast you can get to 20 and what percentage of grade you can maintain it that matters and more watts and volts will do that. So look for at least a 500w/36v system but 1000w/48v is really good and what I run in my pusher trailer down here on the coast.
