As first time visitors to Mexico City, we wanted bikes to spend a day seeing as much as possible…read more For only 400 pesos (about $20) we rented two bikes and a lock for an ENTIRE day. My Spanish is ok at best and it was quick and easy, we were in and out in five minutes. Pay up front and simply leave a driver's license as collateral. Would recommend if you want to explore the massive Bosque de Chapultepec nearby, there's no way to truly see it otherwise. Easy to find, great location in a great neighborhood. Don't expect a smooth-shifting $1000 road bike but it's better than the heavy bike-share bikes in U.S. cities and always better to support an independent bike shop.

Tiny bike shop, very kind employees. No English but you can easily communicate. Bikes are…read moredefinitely not new or very comfortable but they work just fine. They will hold your ID to ensure you return the bikes but are not strict about return time. Just arrive before close at 6 or 7pm. Ask for a bike lock free of charge.

I was going to be in the DF for a month and wasn't ready to give up my NYC cycling habit. Ecobici…read moreis a great program but I wanted a little more freedom. I looked into renting but such thing doesn't exist here, oh well. After checking out a few places right in the same corner of Roma, I'm happy I finally wound up at Alterbike. The very friendly trilingual owner (sorry, forgot his name!) set my girlfriend and I up righteously with two single-speed cruiser style bikes, along with baskets, lights, etc. We walked the neighborhood a little bit, had coffee, and when we returned to the shop they were expertly set up for us. The total bill came to around $300USD for both -- about what it would cost for me to rent similar bikes for a month in, say, Los Angeles and now I get to keep them! The owner explained that Alterbikes are made in Mexico so prices are cheaper than imported stuff. Personally I liked the idea of keeping my pesos here. Mind you, these are simple, functional transportation. They're not the bikes you're gonna ride to Toluca or break any speed records with. That said, we've ridden these many times from our place in Escandon down to Coyocan, up to the Zocalo and Tepito, etc and they've performed like champs. Alterbikes guarantees their gear for a year, and though I've had to make a few little adjustments and tightenings along the way, I'm happy to report that after three weeks of hard riding I haven't had to visit the shop again for tune-ups (More than I can say for the far more expensive bikes I purchased back in NYC!).
