My new ride

As promised, here are a few facts & thoughts about my new ride, the Giant Twist Freedom DX.


First, the facts:
  • Giant calls it a hybrid bike, presumably to liken it to the hybrid cars like the Prius. Though for the rest of the industry, a hybrid bike is a cross between a road bike (think Tour de France racing style) and a mountain bike, so this is a little confusing.
  • Like the Prius, the bike turns battery power into torque to help propel the bike and rider forward. In theory, the harder you pedal, the more assistance you get.
    • Unlike the Prius, the batteries do not regenerate while coasting downhill.
    • The bike has an electric motor integrated into the front wheel.
  • There are four settings: Off, Eco, Normal, and Sport.
    • Sport mode assists the most and Eco the least.
    • When the assist system is Off, you get to feel what it's like to pedal a 62-pound monster of a bike. I assure you this is no fun, and I only have the system off when I'm rolling downhill.
    • Unlike some motor systems like the BioX (my brother just got a bike with one of those), there is no electric throttle -- so you can ride it like a moped. No peddling = no go.
  • You switch manually between the two batteries.
  • Giant estimates the range thusly; these numbers seem a touch optimistic to me. Either that, or I'm a lot fatter than their test rider. In practical terms, a single battery lasts me about 30 miles, or call it a commute and a half on a route like this one with a few hills.
Now some thoughts after a couple training rides and 3 round-trip commutes:
  • Overall, I quite like my trusty new steed. It will help me get in shape, and having the electric assist available will get me onto the bike more often than not.
    • Without it, I probably would not have started commuting by bike. 
    • I'm proud of the distance I've biked and look forward to some pounds coming off.
    • Never before has arriving at work or at home seemed like such an achievement!  :-)
  • The bike is a beast. Something about the size of the frame makes it seem very large. The good thing about this is it feels more stable on the road. But it is a 60+ pound monster, no two ways about it.
  • How's it feel? The best way to describe how the bike feels is to say that it "flattens out" the terrain. Mild uphills feel like flat terrain; steep uphills feel like moderate uphills.
    • I still have to work hard to get up 5% grades like Ralston Avenue -- but the electric assist makes it do-able for me without having to hop off and walk, or take a break.
  • Riding position. The bike's geometry puts you in a very upright riding position, which takes pressure off your wrists and back since you're not hunched over.
    • OTOH, sitting up straight with a loose T-shirt on basically turns your body and T-shirt into a sail. When the wind is blowing against you, this is not good. :-)
    • This posture also makes it harder to get the right kind of leverage when peddling up big hills -- it's hard to come off the saddle and put your whole body into the effort.
    • In general, I like this riding posture because it's relaxed and doesn't make my arms numb after a long ride. This is why I didn't get the very cool folding Swiss Bike with the BioX conversion kit like my brother -- the Swiss Bike's geometry has you bent over more, and I wanted a mostly comfortable posture for the commute.
    • Sidebar: if you do want a Swiss Bike + BioX combo, visit the great folks at Velolectric Bikes in San Carlos. Very friendly and knowledgeable.
  • I'm glad I got the 2-battery version. Giant makes a cheaper and lighter 1-battery version, but I've had a battery run out of juice on half of my rides, and being able to flip to the fully charged backup battery is a huge relief. The thought of biking up the 92 pedestrian path on my 60+ pound monster with no electric assistance brings tears to my eyes. :-)
  • The saddle bags are useful but you need to pack carefully. The built-in saddle bags are really designed to protect the battery packs. But you can get a change of clothes and your lunch into them if you pack carefully. I've been wearing a backpack to carry stuff that won't fit (like my laptop), but am investigating ways to mount something on top of the racks to get the weight off my back and prevent the sweaty back phenomenon.
OK, more later. Leave questions in the comments if you have them.
