Thanks Court! Just from memory, most of the brands had 20 to 30 surveys. I can break out the actual numbers once I get a chance. The dataset is somewhat limited with only 542 responses so the data could be skewed due to the limited data set. I don’t recall any one brand having an unusually...

Agreed! It would certainly help normalize the data.

I have now limited the survey to only one survey per device in a effort to prevent any fraudulent respondents. However, you could certainly take the survey with a different device for each ebike you own. The more data, the better. To be clear, I don’t believe I had any fraudulent responses in...

I will add it in above in the original post, thanks for the reminder. I had included it on the Reddit post but forgot to do so here.

I always need more coffee! Sorry, I added that to the thread on Reddit but forgot here. There were 542 responses in total. Most brands on the list had 20 to 30 respondents.

I should have added that any future survey responses will be included in the next report, which will be out this Fall. I may add a few questions and make some other small changes to the survey between now and then but I can still include responses before the survey change.

I had thought of this too. I did not track dates of failures. And I agree. Any new bike, like the first model year of a car, might be less reliable. And this is even more true for a new company altogether. It would take a lot more survey questions to sort that out and even more responses...

yes, you can take it here: https://ebiketestlab.survey.fm/ebike-reliability-survey

I was very surprised with Specialized and most of the survey respondents were commuters, which shouldn't be that severe of a usage profile (more so than a recreational path rider but less so than a trail rider).

Good points. I'm not aware of any information regarding how many of each ebike are sold but if anyone does know, that would help to normalize the data. I did rate the failure as minor, intermediate, or severe. A minor failure would be a brake light switch, an intermediate would be a spoke...

Added in usage data and a component failure summary from survey in original post.

Thanks for the suggestion, I'll try to do that for the next iteration.

It is still open. Anyone can take it at anytime. I'll post it again in September or so and can pull all of the responses from now forward.

With the somewhat limited number of responses, the results could change significantly with more data. However, the ranking scam certainly be used as a guideline. For example, I wouldn’t purchase a Specialized when lower cost makes are doing much better with reliability. I’m not aware of any...

Here are the results of the first ever Ebike Test Lab Reliability Survey, which we plan to do every Spring and Fall moving forward. The rankings are based solely on the survey responses. An algorithm was developed to take into account the total number of miles, number of failures, severity of...

Yes! I should have the results compiled and a report posted later this week.

After several hundred surveys, Specialized is still near the bottom of the ranking, which still surprises me. Juiced is about mid pack and the leaders are not too surprising: Riese and Muller, Pedego, and Wattwagons! I'd like to get at least a thousand surveys before I publish an official...

Thank you!

Thanks! I'll check them out. Sometimes forums have limits on posts with links, if I can post it there, I will.

Mike, I agree that a quick repair or part replacement by the manufacturer or dealer is helpful and my calculations do use the dealer support and manufacturer service from the survey. However, the largest emphasis is placed on the number of failures vs. the number of miles. The severity of the...
