Even though the company is called Bonza Bike Tours, they actually have a very affordable and accessible hire service. It is very easy to find, considering it is so close to Circular Quay train station. The staff are friendly and will bend over backward to help (yes I mean you Tess!!..oh and I did end up finding my Ray Bans.. Keep the Mints and Chocolates :) ) I hired the tandem bike with my 7 year old Daughter and had a great time taking her over the bridge to Luna Park and then back over to the Opera House.. all in under 3 hours. The service in hiring is not tedious, a few forms and we were under way. You pay upfront, so you know what you are in for cost wise. I had a flat tyre at the Opera house, and the staff changed it free of charge when I got back.
You get free sunscreen, bicycle lock, spare tube, wash facilities, wifi and LUGGAGE storage. ( Omg life saver.. it is $13-16 at the train station alone saved )
Oh I they let me charge my phone when I got back.. what else can you ask for but good old customer service. I would highly recommend it to locals as well as tourists..
oh.. and ask them about Wobbly Wheels.. the unofficial tour :)
Best of Luck
Keep up the good work
Cheers
