Mike,
We have the 2016 Jumper Pro on floor and you're correct. They do not have a throttle. Normally, throttle on mountain bikes is not looked upon favorably. So, they have decided to remove it completely but their city bikes do have a throttle.
There are some nice features for the 2016 model year.
- 500W, 48v motor instead of 350W,36V ones.
- Battery capacity is now 526Whr instead of 432
- Rockshox Monarch rear suspension replaces the mediocre Suntour
