Rob, what rear suspension did you add? i replaced original seat with large spring suspension seat, but probably need rear susp stem too....did you add stem extenders for the handlebar assembly? Id like to raside mine only 1-2inches, if cables allow it.I have the Ecotric Seagull. I modified it to turn it from a mtb into a cruiser. I added Jones S, handelebars (Jones Bikes) and it all to comfort level. Addd a big cushy seat and added a good seat suspension as well. Now I have front and rear suspension. The tires that came with the bike went flat too much so I added kevlar tires that are near puncture proof. With fenders and lights, this bike is near perfect for me. I did have to replace the control unit, and battery, but Ecotric sent them to me, no problem. Still under warranty. I weigh 250 and can go 28 mph just like you said. I keep it in pos 3 and I can get around 40-45 miles on a charge with hills along the way. The battery works alot better in cooler weather. Better milage between 66-70. Great bike for the money for sure. Lots of fun!
