We're very grateful for our early Kalkhoff customers - you took a chance on a new brand and helped establish 50cycles as a big name in electric bikes.
We know many of the first Kalkhoffs are still on the road, often with their original batteries.
However, many of those batteries are now at (or near) the end of their useful life.
Sadly, the original 10Ah and 18Ah batteries have long-since sold out, with no like-for-like replacements available.
But we now have great news! We've found a replacement battery pack that passes three important tests: Good value (price per mile)
Excellent capacity (more than double your original 10Ah!)
Compatible with older bikes and chargers (no extra costs)
So, if you own a 2007-2012 vintage Kalkhoff Agattu, Pro Connect or Tasman electric bike with the Panasonic motor system and battery, but your bike's battery:
Has given up the ghost completely
No longer charges properly
Works, but with limited power and range
Hasn't been used for a while and may have gone stale
Prevents you from selling or handing-down your bike
We now have an up-to-date, super long-range, well-priced alternative that can more than double your range, without costing twice as much. This will give your bike years of extra life and many, many more miles of hassle-free cycling, just in time for Spring. Plus the extra range means you can ride further than ever before and charge less frequently.
