Poor battery quality, poor customer services and misleading marketing.
Had my Max kit on my Brompton for almost a year. Overall I’d say this is a cheap and poorly made product. Took ages for it to be delivered, well past the estimated date for delivery, took a complaint to get them to do something about it, but communication was poor. Within 6 months the LED display broke and had to be replaced. Having owned it for a year, using it 3 times a week for around 4kms each journey, the battery is showing signs of wear, charge is noticeably worse, displays on the LED control and battery are inconsistent and don’t really tell you what your battery level is. I wouldn’t buy this, it’s decorated as a great product and they have done some cleaver marketing to hoodwink you into buying one, likely knowing it’s not up to any real quality or standard you would expect as an average consumer. There marketing in my view is misleading.
