Hi Dave! There seems to be a lot of interest in the
E3 Dash and I can understand why considering the more powerful 500 watt motor, medium and large frame size options and pedal assist plus throttle mode. It was one of the smoothest ebikes I rode at Interbike this past year and one of the highest rated IZIP's I've reviewed because of the value it offers. I think it would be a good choice.
Top echo your last comments, there is something special about the Neo line. Their frame designs with integrated batteries are wonderful and their LCD computer are some of my favorites - being simple and removable. Vern made some great points about rolling efficiency with narrow, smooth tires but indeed they are less forgiving. Mountain tires provide more are volume which reduces shock and the rubber nubs also create a forgiving feel. That said, they don't provide the same traction and may slide out if you're riding higher speeds taking sharp turns (this has happened to me, actually hit my face on the ground I fell so hard then slid into a pole). Be very careful when riding at speed if there is any water on the ground or grass that you may come into contact with, this is doubly true for bikes with higher battery mounts... I crashed another ebike just leaving the parking lot of my apartment one morning, the humid air and oily parking spots did me in.
Crashing aside... I finally settled on the
Neo Jumper for my daily commuter because the power is great, top speed is still ~27 despite knobby tires, and the full suspension is wonderful. It offers both throttle and torque sensing pedal assist and is relatively light weight. The warranty is also pretty good and I like the way it looks. Even though I'm riding on pavement and sidewalks to work each day, I really appreciate the extra cushion because my back and neck get sore and I tend to carry my laptop and other gear in a backpack vs. using panniers. I'm not sure you can even add a rear rack on the Jumper unless it's a seat post mounted rack. It also doesn't have a kickstand and I wasn't able to find one that would work with it. To Ravi's point, I have test ridden the
650B which has 27.5" tires vs. the jumper's 26" and it's a wonderful bike (bunch of Easy Motion reviews currently in the works). I'm not sure if that one comes in large or not?
As for the motor and battery amp hours. I believe that the 350 watt geared design used across the entire Neo line is very capable. The spec isn't very impressive sounding but their drive system seems tighter and more thoughtfully chosen, it's like they custom built and chose components that would maximize power despite and reduce weight. I've loaned my Jumper to a larger friend (6'2" ~200lbs) and he was very impressed. It had no problem hauling him up a parking garage and he really enjoyed the pedal assist mode The frame size is the biggest question mark with the Jumper only being available in medium. The
Neo Cross and Neo City are both available in large and would be good options worth considering. I guess I'm just playing devil's advocate here, all of the bikes we're talking about are great and I'm a fan of the Dash which also offers a solid warranty... and that handy dandy kickstand
