Aurora Limited Edition Mid-Drive Review

For those of you experiencing popping/snapping/skipping issues, what I would suggest is getting a friend and a gimbal camera (DJI Osmo Pocket or similar) and see what you can record on video. That will help tremendously to see if the belt is really skipping and whether it's skipping at the front or rear. If you can mount the camera to the frame Court-review-style you can actually see the drivetrain pretty clearly.

With the bike we had (it was for my wife), I was convinced it was the rear, but a LBS (R&M dealer, btw, so they have experience with the Nuvinci) mechanic was pretty sure it was the front, and so probably the motor. Evelo was VERY helpful and supportive; they sent parts and tools and paid for the LBS's repair attempts, but it simply wasn't working for us. In retrospect, I wished we had tried cranking the tension on the belt up a huge amount just for a short time to see if that eliminates or at least reduces the frequency of occurrence.

What attracted us to the ALE was its ergonomics. The step-through design, upright riding position, and easy to twist electronic shifting with hydraulic brakes are great features that almost no other bike has together, except the more expensive R&M Homage (which doesn't have a throttle). The Gates belt was just icing on the maintenance cake. Besides the skipping issue, we weren't happy with the weight, the efficiency (try pedaling with the power off and see what that enviolo sucks up), the battery capacity (see efficiency), how the belt is tensioned, and the 26" tire size (which the display didn't support in our version). We could have suffered through those if the skipping weren't such a problem. We ended up getting a more expensive bike which I've modified with stem, handlebars, brake and drivetrain upgrades to make ergonomically (if not economically) suitable.

That said, Evelo is a great company to buy from. If you are hesitant to buy from an online company, my experience is that Evelo will support you.

So was it the motor or was it skipping at the front? I think my problem is the motor and I'm getting very concerned because now the noise has increased and occurs almost every time I pedal, even if gently so it may be a motor shaft issue. I may still try the gimbal camera with the belt guard removed.

I do not know.

I should also point out that the Nuvinci enviolo hub has two really nice properties:
  • It doesn't have specific gears, but has a continuous range. I posted a cut-away video of one in action on one of the threads in this forum that's worth watching.
  • You can shift under load, unlike most other IGHs.
