I know this forum is not often used, but there are about 2 forums where I can write about this bike.
First of all, I wanted to tell you that this bike is a great bike!
The battery life is a little short though (it rides ~22MPH, and 35-45MPC (Miles Per Charge); that means this bike is only going to drive you around town for 2 hours!
That is not very much!
Secondly, when the batteries are fully charged, I can get a top speed of 23.6 MPH out of it! I'm a skinny guy; and mainly live around flat land, so the torque of this bike is more than enough!
The top speed is very limited! At 23MPH, I can still drive on 30MPH roads, but will have to drive on those roads with lots of stop signs, at every corner.
At lower than 23MPH, even on 30MPH roads with lots of stop signs, cars are passing me by.
I added a secondary battery in parallel.
I did so by plugging it in the primary battery's charging input.
It keeps up the voltage a bit longer.
The spring system of this bike, is really bad. It's way too hard for a guy like me, and driving over railroads at full speed, makes the front wheel jump!
The back wheel spring system is set too hard as well. It works nice when my wife joins in.
Our combined weight is ~300LBS.
So this bike is either for an overweight person, or two skinny people.
However, when my wife is with me,the brakes of the bike don't work very well! I would opt for better brakes, especially when you want to mod this bike to go faster than 20MPH!
This bike has regenerative breaking! (unlike what others wrote online)
When releasing the throttle, the bike reduces speed ~1MPH/s. When pressing lightly the brakes, after 1 second, regenerative breaking kicks in, and operates best, when driving fast. It operates all the way to ~2MPH, after which regular brakes will do the rest.
Regenerative breaking works simultaneously with regular braking, both on front and rear brakes. It works best when pressing the brakes lightly, so that less energy will be lost in real braking, and more energy will be absorbed by the motor/battery.
You can see regenerative breaking operating when looking at the fuelgauge. The fuel gauge will actually go up when braking (from a position which it would be in stand still).
The generated energy gets loaded in the battery, and in the stop light of the bike.
This probably could become an issue, as Lithium batteries are not really meant to be charged this fast.
On average the 700W motor would be generating almost 14 amps of power!
This power would be distributed to the stop lights (using ~40W each, or a good 1-2Amps of power. The remaining goes to the capacitors in the controller, and the battery.
This could be an issue, seeing that the battery only charges upto 700 times, meaning every time you brake, you are using up these cycles somewhat.
Putting a battery in parallel makes that it absorbs the power much better, and much more effectively will handle the regenerative energy.
Aside from these issues, the mirrors of this bike are also complete crap!
Every time I hit a pothole, the mirrors flap upward, and I always have to re-adjust them, even while driving!
Also the front windshield is pretty useless. It only covers upto the chest, and the bottom of the windshield is re-molten plastic; that is very brittle! When installing the windshield it's inevitable that you damage (crack) the windshield; just to install some rubber sealings! This is unacceptable!
Aside from that, this bike is ok in the city-city, meaning right downtown; but not good for the suburbs.
In Florida electric bikes are allowed to go upto 30MPH (probably because of so few accidents with them), in other states you are limited to 20MPH.
Taking a sharp corner at 20MPH is really dangerous, as the bike is not very maneuverable at these speeds.
The good thing is that they made the pedals very removable! They used some locking mechanism, that by force of hand, one can easily, and quickly remove the pedals.
In South Florida, cops don't really care about the pedals. And for your own safety it's better to just stow them in the helmet compartment in case you ever need them; but on average, it's better to get rid of them; as they are a danger when making corners.
This bike is not an exception. Nearly all electric and gas scooters that have pedals, the pedals are a constant danger when turning. They touch the road while cornering, and could cause some nasty falls!
The bike has some nice storage space, but could have gotten a little more. On the sides of the back wheel, there's still too much unused space, that could have been converted to storage space.
If it was upto me, I'd get rid of the dual shock system on the back, and install an adjustable single center spring/shock system like with modern motorcycles.
The spring in the place of where the controller is built now, and put the controller just like on the 3000/4000/5000li bikes, on the side, just as if it was an exhaust.
I would also build in the charger, as a digital charger does not weigh a lot.
I would also use more space on the bottom (where the battery is located) to store more batteries.
Lower center of gravity is good for this bike, as because it does not feel very solid and stable when driving slow.
The tires that come with this bike are very nice looking, but have almost no profile on them to exit the water.
I suppose it's ok for 20MPH travel and basic peddles; the bike does not go faster anyway.
For the rest, this bike looks good, and when the batteries are fully charged, makes for a nice ride in a nice breeze!
