For the sixth year in a row, a London couple's labour of love will see hundreds of bikes matched with riders who need them.

Monica and Shayne Hodgson's non-profit social enterprise, Big Bike Giveaway, is made possible by Londoners donating bikes at the city's EnviroDepots, and then tuning them up into road-worthy condition.

"We're looking at hundreds of hours in a year," said Monica. "Of the 438 bicycles that have been repaired this year," she said, "the majority" are repaired by her husband, Shayne.

Volunteers help out throughout the year, she said, but it's a small group. They also take in bikes from local Walmart locations that are no longer saleable.

"We don't have children, so our child is Big Bike Giveaway," she said.

Registration starts at 9 a.m. Sunday at the Argyle Arena, 1948 Wavell Street. It's first-come-first-serve, according to height. Children three feet and under are first to receive their bikes. Everyone else will be sized up, then matched to a bike that will be tuned.

A limited number of helmets are being given away through CAN-bike, LHSC Road Safety and Helmets on Kids. They'll also provide proper fitting.

The family-friendly event will also include health and safety information from the Middlesex-London Health Unit, children's activities and bike tune-ups from local organizations and businesses.

Anyone interested in donating a bike to the Big Bike Giveaway for next year can do so by dropping them off at any of London's four EnviroDepot locations. Monetary donations are also accepted for purchasing parts online.
