The extreme cyclist had reached Khandyga in the Sakha Republic while en route to the village of Oymyakon, considered the coldest permanently inhabited place on the planet.
Temperatures drop below -50°C in the village, which has a record low of -71.2°C.
The Polish adventurer set off on the expedition on 25 January.

He planned to cover a distance of 568 miles (914km) in the harsh Siberian winter.
Adam was registered in the local Russian security system and was being monitored with a GPS tracker, according to the Yakutsk Rescue Service.
A spokesperson said: “He stayed at a hotel, went to bed, and did not leave the room in the morning.
“He was found dead at 5:10pm. Investigators are working at the scene.”
Adam shared updates of his trip on social media.
He reached Yakutsk on 18 January and took part in local activities, including an ice-hole dunk to celebrate Epiphany.
He then spent two days camping on the Lena River to prepare himself for the extreme conditions to come.
Adam said: “I already know it won’t be easy and it will be the most difficult experience of my life.
“I have some minor health problems.”

He added: “I hope to return safe and sound.”
Asam also noted that temperatures were expected to drop below -40°C.
He reached Khandyga on 31 January and checked into the hotel.
He posted “I’m in Khandyga!”, went to bed a few hours later, and never woke up again.
Adam spent 18 months preparing for the trip and acquiring all the necessary permits to enter Russia.
He said he viewed the expedition as a spiritual challenge, as well as a physical one.
The Russian authorities are investigating the exact cause of his death.
Adam was an experienced expedition cyclist who had previously traversed the Atlas Mountains and the Sahara in northern Africa, as reported by Need To Know.
He had also cycled through passes in the Himalayas at altitudes of over 16,400ft (5,000m).
