Easy Motion Neo Carbon engine problems.

[opimax]

Same w/my Stromer but certainly not 1/2 . It feels like it some days when I am on the 3rd battery but I know it's not .

On my wife's Stromer we have had some thing similar. But was less than 1/8 strength, some thing was wrong . Removed all connections and both batteries (display and main), let sit and reinstall... Rebooted basically, so far so good

I experienced something similar today on my neo jet 2014. Around 18 miles into a 25 mile ride the bikes assist suddenly halfed. At the time it went out I was in Eco mode on the crescent path in dc which has a slight assent. I could still get assist, just needed to use sport since eco became near useless.

I problem went away after stopping to get a coffee.

To me the problem felt algorithmic. As if the controller hit a bug that made it half the torque input. Or perhaps the torque sensor failed. Speed was reported correctly so that can be ruled out.

I just hit 500 miles and this is the first time to have this particular problem. On a bike that is about 45 days out of the box.

Allen You should not have to jump through all the hoops you are to get assist. It is certainly a failure of some sort on your bike. I wonder if we are experiencing the same issue as when the problem surfaced today Eco became near impossible to get assist since the assist cut out nearly instantly.

I'll be calling bh on this one.

This is a minor glitch that our customers talk about. It's not really a failure of the torque sensor or the motor, it is simply a minor glitch in the system.
Sometimes, for various reasons, controller delays the signal by a few milliseconds and defaults the system to "no assist".

Solution is to completely ease off on the pedals and toggle through "no-assist" mode back to whatever mode you were using. In some rare cases, you'll have to restart the power console. 99% of the time, this will resolve the problem.

Hope this helps.

Both Easy Motion and Stromer bikes use the same TMM-4 torque sensor, which are very reliable. Although, Stromers feel smoother because of the gearless design and the controller programming. Please do not tighten the torque sensor screws without diagnosing the problem correctly. We had a customer who did that and it was a whole new problem.

I was at near full power so we can strike out lack of power. Also after my coffee the bike resumed normal operation.

Hi, eDean.

I had difficulty finding this, my own thread which I wanted to update. So I'll update, first.

After finding that that I could get my ebike to perform properly when I started out using the turbo, then switching to another assist mode, all my problems with the ebike disappeared and I no longer had to start it off with turbo for it to work properly. Today, for example, I just turned it on and rode up a long, steep hill with a gradient of some 15 degrees plus, reaching speeds in the low 20 kph. There has been no recurrence of my previous problems with the ebike and I have taken some very long rides on it very successfully.

This is in direct opposition to my previous experience and I have no explanation for why the ebike just started working properly after weeks of trouble.

But to your experience, it seems to parallel mine in that some time had to elapse from when the controller was turned off until turning it on again made things right. You went to get a coffee, suggesting that some time elapsed before your ebike worked properly again.

The problem may, indeed, be related to something with the controller but not in the usual line of controller problems. My ebike problems didn't go away with change to a new controller. The controller still showed everything was correct even when the motor was cutting out. It was like the message from the controller was not getting to the engine, and this could be the algorithm problem you suggest.

But, as I said, my ebike problem has disappeared and I have no explanation for why it did so, or why it was having problems in the first place. I just hope it never returns, and that yours never does, either.

Allan, I must tell you that you have a problem that will probably return. My Neo Carbon simply works in all situations. I suspect that your torque sensor is defective or you have some intermittence in your cabling. Every product no matter the vendor or build quality has problems from time to time. Easy Motion technical support is very supportive and will talk to end-users. Unfortunately problems just don't disappear. If the problem raises its ugly head call Marc at Easy Motion tech support as he will work through the problem with you and the dealer. He has very good customer service skills.

Allan, sorry to hear about the problems you have been experiencing with your NEOCarbon. The problem you are experiencing is not normal and you should be able to climb just about any hill assuming you are willing to continue pedaling a bit while climbing. Some hills will require boost mode and a good bit of pedaling to comfortably get up the hill (say a 15%+ pitch which is pretty steep). Our controllers are designed to cut the power to the motor if the controller overheats which can happen on a steep hill with little or no pedaling.

The controller is mounted to the frame and in our other bikes with aluminum frames, the frame acts as an additional heatsink.. The Carbon has bit lower temperature threshold since it does not dissipate heat quite as well, but you should never need to get a running start just to climb a hill assuming you are in the right gear to begin the climb. The Carbon is one of my favorite bikes in the line and I have ridden it off-road and on and have climbed some the of the steepest hills you can find w/o any problems.

I would take the bike to your dealer and have them re-set the torque sensor, test the bike out and if that does not do the trick, it could like be a problematic controller. In any case, I'm confident we can get your bike performing as it should.

Hope this helps!

After much tribulation, and through a process of trial an error, I have finally figured out how my Neo Carbon ebike works.

If I have a hill to climb, I need to start out with turbo to gain speed. Then, at a certain velocity, the ebike can be switched to Sport or Boost. The gears must be set to medium levels or higher when doing this and it works best if I’m already pedaling as I switch from turbo to a higher assist mode.

If the gears are too low the motor will start but then immediately quit. If I apply too much pressure on the pedals the motor will quit. And, when in either Sport or Boost and I need to make a turn, the motor will quit if my speed drops to less than 10 kph. (Quit means no assist mode kicks in and turbo is dead.)

Using the above approach, today I climbed hills and went over the Golden Ears Bridge with ease.

Interestingly, on flat surfaces I can use Eco and Standard relatively successfully if I keep pedaling with no strain put on the pedals and the ebike is in higher gears. However, I often take my time on flat areas to look around for eagles and to take in the sites. As this requires very little pedaling neither Eco nor Standard activates. This inactivity seems to be responsible for the motor going to sleep and not engaging when I do start pedaling. Further, turbo won’t come on so I have to turn the display off and restart it. Then I must again use turbo to ensure the ebike will work properly. In other words, it seems I must be actively pedaling to keep the motor working otherwise power to the motor stops, even though the display says everything is fine. And I must be at a certain velocity, too.

Now I gather other Neo Carbs do not function the way mine does, so maybe there is some problem with my particular ebike that puts it to “sleep” when it shouldn’t, but the good news is I now know how to operate the ebike so it will work and so I can climb hill and dale with confidence. And, now that I have the exact information on what the ebike is doing I can go back to the dealer to see what his mechanic thinks this all means.

Thanks Steve, Flymeaway and Mtnm for your recent input. I will put it all to good use.
