New Aurora 2019 Model

#1
Just got the new 2019 Aurora Evelo delivered a short time ago. Great service from Evelo to have it delivered to my place free and assembled. Said it was the very first bike sold for this new 2019 model year, as the rest will be on their way soon to the USA.

While I was a bit hesitant to buy the first ones in a new model year, at a new factory, since it can take some iterations to get the kinks out, I took a chance and keeping my fingers crossed. Evelo does seem to have a good reputation.

I had a checklist of things I wanted in an Ebike and had a hard time finding a bike that checked enough of the boxes. I wanted a step thru, class 3 that could also be used throttle only and could go over 20 mph, internally geared hub, front suspension, hydraulic brakes, a bigger powered motor that can handle some hills with no issue, good sized battery that could handle longer rides, not too big frame size, fenders, rack, had a good reputation and service, an appealing style, and more of an integrated battery frame design, rather than a design where it looks like the battery is attached to the frame as an afterthought. I found the Evelo Aurora and this bike checked the most boxes for me.

I ordered the upgraded Aurora model with the 750W motor, NuVinci Harmony electronic shifter, and hydraulic brakes, bigger battery.

Some some minor changes in the new 2019 model vs the previous model that I have noticed:

1. Has a different seat that is narrower than the previous model. Looks like a Velo, but not sure on the model. Felt fine so far on a short trial ride, but will have to see how it feels on longer rides.

2. The rear light wiring no longer goes through the rear fender, but is run along the outside of the rear rack tube and frame. I saw in Kort's review where the cable through the fender had broken, so nice to see they changed the design, since the fender will have more vibration and movement.

3. It has a single side mounted kickstand, which is what I prefer, as opposed to the dual center mounted kickstand, which tends to hang very low and takes a little more time/effort to get the bike on the kickstand.

4. Did not see any screw holes for mounting a cup holder on the part of the frame holding the seatpost, but no issue for me, as I prefer not to have a cupholder blocking the step thru.

Only drawbacks noticed so far for me.

1. I already had an idea of before I bought it, but the rear rack tubing is very thick, so while that adds more stability to the frame and strength of the rack, it does not fit many rear rack bags and the clips my expensive Ortlieb pannier bags wont work. I can sort of hook them on with a little pressure that stretches the clips just slightly, but the retractable underclip cant close. And the bottom clip doesnt line up as well to secure the bottom part. But, maybe a chance it is still usable, will have to test it out more. And the rack will also not fit my clip on messenger bag. I will be able to use by MaxMiles top rear bike bag with foldout panniers, since this attaches via velcro straps, but these cant hold as much as my Ortliebs.

2. the speedometer/mileage and informational display is not removable, so I worry about someone stealing this by either just breaking it off or using a screwdriver.

3. the key only unlocks to remove the battery, but does not turn off the power. So, if the bike is parked, anyone can come and turn the power on, lights and even use the bike, if they can cut the locks. So, the key does not add another deterrent. Probably better to detach the battery to discourage theft, but then quite heavy to have to lug around when you are running errands.

4. I did notice the battery life drained very quickly when taking a first test ride, and it made me do a double take with how fast it was draining. With pedal assist on 2, and it was dropping about 1% per minute and even a little faster. Also, noticed that afterwards when the bike sat awhile, then turned on the display, the battery charge pct. climbed back up a bit, but not back all the way to where it was before, and still more of a drop than it should be. Hope this issue was due to the battery needing a first long initial conditioning charge. I did not get the charger with the bike yet, so I could not do a long first charge as recommended, but will do that as soon as I get the charger, which is being sent to me, so probably within a day or two. But, hope there is not an issue with this battery getting drained so quickly.

Overall, first impressions are very positive, except for the battery drainage problem. Very sturdy, and solid feeling. Rides nicely. Love the NuVinci Harmony thus far. In automatic mode, quite convenient for leisurely riding to just pick the cadence you want to maintain and it adjusts the gearing depending on the pedaling speed to try to keep it the same. And when you come to a stop and restart, you dont have to worry about shifting at all, just set it and forget it. And add in the pedal assist and you can maintain the same cadence with little effort. Really convenient for leisurely riding, especially when you have frequent stop and starts.

Will report more after I ride the bike more.

Once you fully charge the battery you should have no issues with it draining too quickly. In the unlikely event that you do, the folks at Evelo will most likely take good care of you. The Velo seat on mine is pretty comfortable but I added a suspension seat post to make it even moreso. I also added a stem riser and swept back handlebars to sit more upright. One more recent addition is a thumb throttle that attaches to the stock twist grip. It is much easier to use. Best of luck with your new Aurora. :)

There is likely no battery drainage problem. What you are witnessing is a very rough indication of how battery capacity is measured, meaning they use voltage. Overall, the best way to check is to do a full ride, and stay in level 1 or 2 on a fairly flat terrain with no wind, and you should get close to the estimate depending upon your leg strength and body weight. As soon as you add hills, start seeing headwinds, or letting the motor do majority of work, or move assist up to level 3 , 4 or 5, the range is going to drop. With that bafang 750 and 11 ah 48v battery you could get up to 40 miles if your weight isn't over 175 lbs and using level 1, making sure you aren't just 'ghost pedaling'. 750 watts is a lot power, so people can have a tendency without realizing it, to let the motor do more of the work, and since there is not a torque sensor built it. That is typical of cadence sensing. If you watch the wattage use during your ride, maintaining good human effort, to keep watt level low, you'll get longer range. On the plus side, despite the high watt rating , the bafang is higher torque even at lower speeds, maintaining a good efficiency and so on other brands of ebikes and using the same motor on my conversions, I've gotten as much as 50 miles on a 11 ah 48 volt battery. Not too shabby. It's not a Bosch or a Yamaha in terms of efficiency, but then you are doubling the cost on what the manufacturer pays for the Bosch or Yamaha or Brose vs the bafang. Bafang is also super easy to service, and very easy to get parts, and they are reasonably priced. But with a 4 year warranty, you won't have to worry about that for a long time.

Thanks. I am still waiting for the charger to be delivered, so hope it gets here soon.

I sure hope this is not normal battery usage, as it was dropping very fast. I am only about 135 lbs, so that should help, and only did a short test ride for maybe a mile or so for about 5-10 min on flat roads and it dropped 10%, with a mix of some ghost pedaling and harder pedaling, at assist levels of 2 or 3, and tried a couple short bursts throttle only, but also some coasting, so overall still very minimal riding. At that rate, would only be able to ride about 1 hour, which would be a huge disappointment. Wondering if I should have gotten the 500W motor option, but then I would have had to give up all the other upgrades and I really like the upgrades. But, will wait to see how it is after I charge it up with a good initial charge.

My 2018 Aurora does not drain battery at anywhere near those levels, it stays on 100% forever and then slowly goes down but so slow you can't really see it happening. I have never ridden far enough to deplete it but I feel it has a pretty good range.
 
#7
Thanks Jerry. I was optimistic that it would be better after your post. But, I finally got the charger and did an initial charge of 12 hours (actually around 13 hours) and was hopeful the problem would go away. But, then did a quick test ride of 1.2 miles over about 5 minutes of mixed riding, flat road and it dropped from 100% down to 85%. Then, rode it another couple of minutes and it dropped to 84%, so a bit slower than first part. But, overall, very disappointing. I assume something is wrong with my battery. Ugh.

I would contact Evelo because in my experience they will go overboard to help, sounds like a defective battery to me, I rode mine about 30 miles initially when I first charged the battery and it only dropped to 48% and then I recharged it. The 30 miles was over a few rides span not all at once. I recharged it about a month ago and have only been able to ride about 5 miles since with some hip problems but it is still at 100% now and has not drained at all mounted in the bike. In the winter I kept it inside but the last few weeks just leave it on the bike as it is warm now. Give them a call and I bet a new battery will be on it's way in short order.

Yep EVELO is responsive and good on service.

Thanks. I did get a reply from John at Evelo below and yes Evelo has been helpful all along the way thus far. I dont think it is the display gauge itself, because checking the battery charge on the battery itself with the 5 lights also shows a similar fast drain that seems to align with the % reading. I will try the depletion and recharge suggestion below and see if that fixes any "sleeping cells", or if it is just a faulty battery.

"There are two possibilities here with the battery: one is that the battery may need to be fully depleted a couple of times and re-charged. Sometimes there are sleeping cells in the battery that can prevent the battery from getting fully charged, and running the battery down and recharging will typically sold the issue.

The other thing to consider is the gauge itself, which has a good bit of variability; i.e. I wouldn't assume that the number you're seeing will continue in a linear fashion. It's also tied to the real-time current draw, meaning if you're on a steep hill, it will show a significantly reduced percentage--and when you return to flat ground, the percentage will increase.

Here's what I'd suggest: run the battery down to about 20% or so two or three times, and leave it on an overnight charge a couple of times, then report back. If you fear you're getting low on juice, switch it to pedal assist 1 or 2, and the reduced current draw should ensure that you have enough juice to get back. Let me know how the above works out for you and we'll go from there!"

I have a 2018 Aurora that had similar issues, bought as an open box with 108 miles. On flat ground level 1 what does your watt meter show? Ours was at 500 while my Delta in the same conditions would read below 250. In our case Evelo sent a cable and program link to reflash the controller with that and about a dozen charges on the battery things are much more in line with how my Delta performs. I also use voltage readout as opposed to percentage.

Hi Woodie,

I will have to try it on flat ground level 1 and see what the watt meter shows. I assume it will vary depending how hard I pedal, so what kind of pedaling are you talking about? thanks. If trying the depletion doesnt work, I will ask Evelo about what they did for you. Thanks.
 
#14
Thanks. I tried it today, level 1, flat road, easy pace, and it is moving somewhere between 375-500 W.

So, in your case, do you know if it was the reflashing of the controller that helped or was it simply the dozen or so depletions and recharges after the reflashing or both? Since John at Evelo mentioned to try to deplete and recharge a few times because of these "sleeping cells", then I wonder if just the recharging alone solved your issue?

I think in my case it was a combination of the two. For my wife level 1 as delivered was way to fast, 15 mph plus and no peddle resistance. I noticed the fast drop in voltage, like 20% in a few miles. Again riding side by side my delta would be at 250w and the Aurora at 500w. In my uneducated mind I thought too much juice for level 1 = fast battery drain.
Evelo was super responsive to our issue and resolving it.

One other point I forgot to mention on the display. It is possible to password protect the display, so when one tries to power it on, it needs a 4 digit code to get to the display. So, that is a protection that is nice to have, although is a bit of a hassle to do each time you go for a ride, but at least you have the option to either PW protect it or not, so you get to choose the tradeoff.

Regarding the battery, still trying to discharge it then recharge it a few times to see if that improves the fast draining situation. Only have done it once thus far, but will wait and see if it improves. Other than the limited range due to the battery situation, which is a major issue for me, I really like the bike. Really like the internal Nuvinci hub and CVT. Solid ride to it and love the pedal assist, hydralic brakes


I did try attaching my Ortlieb Panniers to the rear rack and kind of slighly forced it on and the clips dont close. Held mostly, but when fully loaded on the way home, one side popped off when I hit some small bumps and ended up dragging the bag and scuffing it up, before I could stop, which was unfortunate. I think I can try to loop one of the straps on the top of the bag to the rack to prevent it from popping off entirely. Shame about the ortlieb 2.1 clips and most any clips made for most racks not fitting the rear rack very well. And the bottom adjustable clip that tries to secure the bottom to the frame doesnt fit so well either. With the larger square rack tubing, you probably need some custom clips. Will have to see how my MaxMiles bag works on the rack. The velcro straps that go underneath the rack will fit no problem, but it has two velcro straps on the front of the bag that I dont think have anywhere to secure them. Most racks have a part close to the seat that sticks up to prevent things from sliding forward, but there is none on this rack. Think I may need to look for some good sized panniers that are connected with a flap that just sit on the rack with no clips, but maybe has straps.

Thanks Jerry, good to know. The capacity doesnt hold as much as my Ortlieb's, but at least I have got something. And do you attach the straps on front of the MaxMiles bag to anything or are the 2 on the bottom of the bag that go under the rear rack all you need?

Curious if you've gotten anywhere with the battery drain situation?

I'm considering a Delta model (which I think uses same motor, manual version of CVT hub) and am concerned about battery efficiency -vs- other brands / models.

I don't plan on doing marathon rides, just casual use, but significant differences in system efficiency (25% +?) is reason for pause I think.

Since the Delta is pretty heavy for a MTB, I'd be relying on motor to a fair degree, and battery depletion rate could be a major point of comparison to other models or brands under similar riding conditions.

I have 860 miles on my delta and for me the battery life is about what I expected for my weight 285lbs and terrain. I alternate between two very different types of terrain, one route is mostly flat paved paths and gravel and I get about 40 miles per charge the second route is dirt trails and very hilly terrain on the nor ca coast and I get around 30 miles there.

I am happy with my purchase and have had zero issues. This was my first purchase and have since gotten much more knowledge on Ebikes and I would buy again.
