Since introduction of E+ I always wanted to try it.
I bought 1000W E+ kit /motor,battery, cables, display/.
E+ is based on legendary Tidal Force which I also own.
At least it is mechanically very similar but electrically is built on different platform.
Both ebikes have Nickel batteries in front wheel.
There are ONLY bicycles in the world whith such batteries.
My review is especially more valuable because I have direct comparison TF - E+ on daily bases, however my TF is not 1000W model.
My adventure with E+ started not so good, because EMS/manufacturer of E+/ sent defective motor to dealer I bought my E+ from.
It jerked/cogged at higher speed from day one.
Thanks to this and other forums I located other owners and found out others didn`t have this problem so I sent it for warranty repair to EMS which was NOT FREE - EMS charges for return shipping to Canadian customers which I found highly discriminatory for non-USA customers. EMS even reimburse USA customers for shipping to them.
So warranty repair cost me $230, on the top of $2600 I paid $230 for repair -
total $2830 !!!!! for ebike kit !!! No doubt the most expensive ebike kit in the world.
After repair my E+ is much more smooth but not so wondefully smooth as TF.
The biggest attraction of 1000W E+ is efficiency,even with high internal resistance of 36V Nickel battery bike draws just above 1000W of power 1050W at most at 48km/h with headwind of 20km/h with light pedalling.
E+ battery with 30 cells 5miliohms/low estimate/ each has 150miliohms of total resistance. Imagine E+ on 12 cells LiFePo battery with 20-30miliohms??????
Clearly E+ is at least 10% more efficient than 1000W Tidal Force.
Motor is around 12 pounds lighter and noticable smaller than TF.
Unlike TF it has disk mounting holes.
Unlike TF with NORMAL and TURBO power settings E+ has 9 power levels which really work very well - it is great future for saving battery power, again they/power levels/ are not gadgets, they really lower power a bit every time you choose lower power setting down to setting 1 which just bearly compensate for rolling resistance and losses of system so it feels like pedalling heavy bike.
On TF I waste some of battery Wattshours , because in Turbo throttle is not really linear and you really have to be careful to not press ikt to much. TF throttle is of course not so bad as Chinese jerking throttles.
E+ throttle is very, very linear, on every bit of pressing you will feel response from motor.
Now negatives.
Regen is not even close as good as on Tidal fORCE. It is much more weak than TF and application is abrupt/clicking, it is more like switch than wonderfully smooth TF regen.
Everytime you reliese break under regen you feel jerk from motor.
It is everything about software implementation - TF regen is noticable stronger when speed is higher, not so on E+ - it seems to be the same regardless of speed ,
at 20mph and higher speed efect of regen is next to none. Not so on TF where regen is very strong and increasing smoothly , very noticable saving your rims from wearing out.
