Background

Zipforce AB, 559079-9663, (the ”company”) was declared bankrupt on November 12, 2025, whereby attorney Peter Eriksson was appointed as bankruptcy trustee.

The company has developed a portable electric motor that converts regular bicycles into e-bikes. The patented e-bike motor is hereinafter referred to as ”Zipforce”. The company was started to create an economical and smart alternative in the e-bike market. The vision has been to electrify existing bicycles, thereby extending their lifespan and increasing their range of use. The patented Zipforce kit is compatible with virtually all bicycle models.

Further information about Zipforce products is available on the company’s website https://zipforce.se/. As of the date of bankruptcy, the company had a Trustpilot rating of 4.7 out of 5, based on over 200 customer reviews. In total, over 5,000 units have been sold, with the Swedish market accounting for over 80% of purchases.

Operations have been conducted from leased premises at Dalagatan 76 in Stockholm. Operations in Sweden have included product development, manufacturing, sales, customer support, and distribution.

Sales have primarily taken place through the company’s own website, which is translated into four different languages: Swedish, English, German, and Dutch. The company has established collaborations with retailers in Sweden as well as a small number in Germany, the Netherlands, and Italy.

As of the date of bankruptcy, the company’s three employees had been given notice of termination.
