About a month ago I decided it was time to reduce my trike inventory. So I decided to keep my Performer Tadpole and Sun EZ3-SX. That meant getting rid of the two TerraTrikes with the DIY mid-drives. Decided not to sell them as electrics because I didn't want to become someone elses electric trike maintenance guy, already have several that depend on me, plus I didn't figure I could get much extra for DIY stuff and old batteries. So on the way to do this, I was looking at trikes on Craigs List in order to make a recommendation to a friend and I stumbled onto this one. It's a Sun X3-AX, basically similar to the Sun EZ3-SX, but with about a dozen upgrades. So then I had 5 trikes.
At this point two trikes are sold, and I've got the NuVincis, 9Cs, and freewheel cranks posted in the For Sale thread, so it's all working out.
Edit: It's a good thing I'm really enjoying this trike. Much nicer ride than the EZ3-SX, which I seldom rode, and I use it for most of my short rides under 3 miles because it's still not as comfortable as the Performer tadpole. But today (May 30, 2017) I discovered the non drive side rear axle is bent a little. Can't see the rear wheels when riding, but thought something was wrong with the disk brake on the right side. When I checked it I thought the disk was warped and noted that wheel seemed to need truing, but on further checking found it was a slightly bent axle just outboard of the outer bearing. A new axle is about $50 so having paid $500 for a like new trike that currently sells for over $2000 is still okay. These axles are only about 5/8" diameter so not real strong. Probably a heavy rider hit a bad pot hole or something, but I'll never know.
Edit: The NuVincis and 9C motors have been sold also.
