The 13th annual Bike Swap will take place this Saturday and Sunday, according to a news release from Animal Allies Humane Society, which is one of the beneficiaries of proceeds.

The swap is from 10 a.m. to 5 p.m. Saturday and 9 a.m. to 2 p.m. Sunday at Continental Ski and Bike, 1305 E. First St.

Those wishing to donate bikes for the event can do so during store hours - 9 a.m. to 7 p.m. - through Friday. Proceeds go to the Humane Society and the Head of the Lakes United Way.

For those wishing to sell their bikes, check-in begins at 9 a.m. Thursday and Friday and concludes between 8 a.m. and 9 a.m. on Saturday. Those who sell their bikes will receive 75 percent of the proceeds, with the remainder going to the two agencies.

Last year, more than 500 bikes were sold, according to the news release, and more than $12,000 was raised and divided between the two charities.
