They go for around PhP 3,500.00 (US$80.00) pre-owned over at HMR in Pioneer St., Mandaluyong. A brand new one costs more than US$200.00 on Amazon. So I got mine for 1/4 of its actual price.
A feature I like is that the trailer can be converted into a jogging stroller! You just unhook the tow bar from the coupler, unscrew the front wheel and attach the metal handlebars at the back. Voila! My wife and I can take Bea around even without the bike!
And another thing, the side windows of the canopy are made of clear plastic. I would've preferred if they were mesh screens like the front and back, so it'll be more ventilated inside. But, oh well, beggars can't be choosy! It just cost me 2,000 pesos.
Special thanks to Bobby Leyeza for selling this bike trailer to me at a really good price!
