New setbacks have again delayed the first deliveries of the “world’s smartest power meter”.
The crowdfunded Limits power meter will not be with backers now until April, some four months after originally promised.
“Our reliability and repeatability testing has shown we needed to redesign the battery end caps,” said Gordon Drummond, Limits’ chief operating officer.
“Also there was some non-linearity of the power data at the higher end of the range and we’ve had to implement a fix by changing the printed circuit board hardware.
“We can’t afford to release a sub-standard product,” he added.
The tests of the prototype meters are taking place in the UK and manufacturing is being set up in Asia.
The added delay is the third announced in as many months and makes Limits vulnerable to other new rivals.
When Limits raised $475,000 (£335,000) through the Indiegogo crowdfunding website in April 2015 it look set to be one of the most affordable products available at $385 (£270) each.
But only this week a new crowdfunded rival undercut it. The Tempo is listed on Kickstarter for $295 (£208), with a delivery date of July.
So Cycling Weekly asked Drummond how Limits could compete against the promise of cheaper offerings while still facing delays with its own production.
“There are additional costs that we have to swallow because of the changes and delays,” said Drummond.
“And we always anticipated that the market would change and that we’d see new competitors. So we have had contingency plans in place from the start.”
The Limits Power Meter sits between the crank and the chainset while Tempo’s rival offering fits to the crank. Both meters are one-sided.
