8 years agoI am surprised that with all of that space between the seat and the rear wheel, that they did not mount the battery on the frame, leaving the rear rack just for cargo.
Being rear heavy might not be such a bad thing. One thing that takes getting used to on a tadpole trike is that you can stand it up on the front wheels when braking hard, just like you can go over the handlebars on an upright bike if you slam on the front brake. It takes a bit to get used to the limits of any bike, and that extra weight in the rear might just keep your rear wheel on the ground a little more often :)

8 years agoYeah, I think one of the other models had a frame mounted battery like you’re describing but no rack. I believe it’s a delta so there are two wheels in the back and the seat is further back which takes up a lot of space. Another design has the battery mounted to the back of the chair in a near vertical position :)

8 years agoNIRMALA: Mounting the battery to the frame is possible, but it limits your seat adjustability and makes it hard to remove the battery quickly if you need to take the battery with you (EX: if you charge the battery indoors but keep the bike in the garage). Anyway, our mechanics can do a number of things to customize your installation if you don’t want the battery on the rear rack, just call us up and we can discuss it. +1 800.375.0224

8 years agoThis is an incredibly well thought out and informative article. Love the bike and not a bad price for all of this. Great stuff.

8 years agoThanks Simon! Glad you enjoyed it, I do my best to be comprehensive but also leave comments open so we can get different perspectives. Looks like you might own a bike shop in New York? What brands to you carry?

8 years agoHey Court,Any idea the size of the bottom bracket on this thing? Thanks
ReplyCourt Rye
8 years agoNo, but I’ll send a message to the Sun Seeker team and see if they can chime in to help shed some light ;)

8 years agoThis bike looks nice. Are there any places in Milwaukee, Wisconsin that have this bike to test ride? I have never ridden a recumbent before, I would love to try this.
ReplyCourt Rye
8 years agoHi Jon! Unfortunately… no, I think they only sell online. It’s one of the reasons their trikes are more affordable but you do take a risk ordering, receiving and THEN test riding vs. going in person. Very few shops around the country sell electric trikes, especially recumbents like this BUT you can sometimes find an unpowered recumbent bicycle just to see how they feel. Check on Craigslist and call your local shops :)

7 years agoHey, watching your video on this bike sold me and I bought one! I’m loving my electric Eco Tad SX! It’s a solid trike, and I’m very happy with the electric performance. I second your comments about the funny interplay between the throttle and the assist level. Took a while to figure that out. But, on my last ride I got the assist to max and throttled it and wow did I go! Still, I wish that throttle would fully work in any assist above zero. I will also say I find myself wishing there was some shock absorption built into the frame. You definitely notice the bumps! Well, enough with writing, let’s get back to riding ;-)

5 years agoHello, I know this is a very old thread. Thank you for such a great review, it answered a lot of my questions. One question I have is, does the seat have to be such an incline or can you make it sit more upright? THANK YOU BILL
ReplyCourt
5 years agoHi Bill, Yes! I think you can adjust the back seat angle. In the photos, I can see holes in the support arms that allow you to adjust the pin so you can extend or shorten them. You can also call the company and ask more detailed questions if you’d like, here is their contact page.
