Traders and transport workers in Sinuiju, Ryongchon county, and Yomju county are modifying electric bicycles for commercial hire. Performance modifications boost load capacity beyond rated limits and raise top speed. These electric bike modifications include reinforcing the frame to carry heavy cargo. Installing higher output batteries increases motor power substantially.
The source said people want to carry as much cargo and passengers as possible. What you earn depends on what you spend on modifications.
Fuel price increases from Middle East turmoil have pushed up transport costs. Beollyi cha private freight vehicles have nearly doubled their fares. Therefore, electric bike modifications have accelerated sharply in recent months.
Chinese imported electric bicycles come with speed limiters installed. China legally restricts the top speed of such vehicles. In North Korea, earnings depend directly on speed. Consequently, many people remove those limiters and install extra batteries. Technicians who specialize in these upgrades are doing brisk business. The mechanics who increase battery capacity earn good money.
Some observers raise concerns about reckless speeding and overloading risks. Vehicle life spans will shorten under heavy commercial loads. Nevertheless, traders face immediate financial pressure. Performance modification is a matter of survival. Therefore, demand for electric bike modifications will continue for the foreseeable future.
