Awful experience today.. we hired 4 bikes, including one of the larger e.bikes, unfortunately we got a flat en route to the Golden Gate Bridge and the ‘customer service’ provided no assistance whatsoever. If anything they made it worse by ignoring us and giving us conflicting information… they wouldn’t speak to us directly (only via WhatsApp) directing us to an alternative cycle shop 37min walk away (which couldn’t help anyway) and then expecting it to be pushed back to the location over a 1.5 hr walk away… This was a 40kg bike, and very difficult to push, without the SF hills! It ruined our day and cost us over $240… We cycle a lot, we aren’t new to bike hire, flats are a common occurrence when cycling and it’s insane that they don’t have a contingency plan in place for when this happens. I dread to think how bad this could have been for someone alone, smaller, or older in the hot San Francisco sun! I can’t believe a cycle hire company would operate in this way, it is irresponsible. We’d have been much better off hiring the bikes available to hire via the on street racks and that just isn’t right… I would never ever hire from this place again and would recommend against doing so if you’re even considering it!

Really enjoyed this tour. John was a great guide - kept a sensible pace, looked out for us all and was full of useful information about San Francisco and the surrounding area. There’s a couple of slightly challenging hills - not unexpected for SF! - but we never felt rushed and when I got off and pushed my bike up the tough hills, I was never made to feel uncomfortable or held the group back. The last bit of the ride down to Sausalito is lovely - and all downhill - so a great way to finish! A lovely way to see some of the City and cross the bridge - would highly recommend!

Unlimited Biking is the place to be for quick service, but surely for some good guide(s). We did the Santa Monica tour before, which was great, but now we know that e-biking around in San Francisco was even better, especially with our (we were only 2, so he kinda became a private) guide John. A lot of historical and economical facts spiced up our (cold & warm) windy and interesting 4 hours together. Ask for John and your tour will be more than worth any tip you could think of giving.

I reserved 2 ebikes online and paid online, as well. When we arrived on time at the Haight rental location, the attendant told us there were no ebikes available and the attendant had no visibility for when the ebikes would be returned. I requested a refund but the attendant told me that he does not have the ability to process refunds and that I need to email sales@unlimitedbiking.com to request a refund. He gave me a hand-written post-it note to attach to the email. I sent at least 3 emails the week following the rental and received no reply whatsoever. When calling the 415-854-2222 number, the agent says they can't do anything and the only recourse is contact through the email. $150 for 2 bikes for 4 hours - wasted!

We had a Great tour with Jody and Sean (student) as our guides. 2 guides for 4 felt like a VIP arrangement. We had a Great time and the Chance to ask all our questions about life in SF and the USA in general.

The tour was great. A big thank you to John, our guide. He was enthousiastic, lots of interesting facts and culture to share and you could feel his love for San Francisco. A great 4 hours to spend. I would recomend it to everyone who comes to SF. @John: thank you for your patience regarding my condition en that I could not finish all the hills. ;-)

Had hoped to rent better quality road bikes for a ride across GG Bridge and Marin Headlands. Booked bikes 3+ months ahead but arrived at the shop at 9am (no one there until 9:15) and were told no road bikes were available. Some one did show up at 9:45 with two very average road bikes and had to scramble around to find tools so we could use our pedals. Bikes had no equipment to change a tire and overall were very average. I would not recommend UB to rent road bikes with the hope of doing more than a short, low effort spin.

Unlimited Biking had the Best Guide and lots of information for us. Thank goodness for excellent bikes they supplied! They stop for short breaks. Bring your own water and a maybe a little snack.

I was using one of the 2 hours free biking rental coupon I got with the new Destination Fee that hotels are now charging for no good reason in San Francisco and well turns out that again there is no free lunch, what was supposed to be an pre-authorization because I declined the insurance is finally charged to my credit card...this is not about the amount 1 USD but about how they proceeded! Unacceptable. Bike was in average condition.

We went from the waterfront to the Golden Gate Bridge and through the Golden Gate Park. We also went down Lombard Street. The trip was 4 hours with a few breaks. We felt incredibly safe and PJ was a great guide and very knowledgeable. Fabulous time!!

Very friendly service, not pushing any extra's, just clearly stating pro's and con's and let us make the decision. Good advice on where and how to bike, which roads to avoid, et cetera. I do think there are cheaper bike rentals available, but Unlimited Biking has pretty new and well-maintained bikes, and multiple locations throughout the city where, should you need it, you can drop by and get a different bike, or tune it up, et cetera.

Employee ran my card before informing about insurance policy. As soon as I saw it, I backed out. Employee had me jump through hoops to correct their mistake. Now I have to send an email somewhere. Gives me incorrect email, so I waste a day and have to return next day to get correct email from second employee. Now person on email says they don’t do refunds and tries to scam me with the old “store credits” scam. Meanwhile they have not provided services, and they don’t even have my signature. Stay away, as this is the kind of experience that can ruin your well planned vacations.

Excellent tour. Weather was beautiful and our tour guid Gerardo was very knowledgeable. All round a great way to see San Francisco

John was knowledgeable, easy going, and really entertaining on this fantastic ebike tour in SF city- highlight of our stay!

We had a great time on the E bikes. We rode all the way to Muir Woods, which was a treacherous ride, but beautiful scenery. We had to take a taxi back to Sausalito. The bikes were great, and we had a wonderful time.
