Sadly, I put my Copenhagen Wheel-equipped bike up for sale today. The batteries will no longer take a charge, no doubt since it has been several years since I charged them. Lithium-ion batteries do not fare well if you allow them to fall into deep discharge. I had zero time for bike riding during the River House construction. Superpedestrian, the manufacturer of the wheel, and where I was head of engineering in 2017, has since discontinued the product and now sells e-scooters for city-wide fleet applications. I have listed the bike for a very low price and disclosed the non-working wheel. For a moment, I considered replacing the rear wheel and brake with the original equipment but when I priced it out, I decided it was not worth the time and effort.
