Patricia, which of the two bikes you have do better on hills? Do you have a quick compare and contrast to offer between the Flow and LaFree? I’m trying to find a place to test ride the Flow but haven’t found one close yet.
The La Free feels more natural to ride because it senses cadence, torque and speed. The Flow (I think, don't have the manual here in WA) senses speed, so the pedal assist is going to go a certain speed, as long as you're pedaling. If you're in PAS 2 or above on the flat, there's going to be some "clown pedaling", no matter how high you gear the bike. With the La Free, I set the PAS to auto and just ride the bike. On the Flow, I use mostly PAS 1 (goes to about 6 mph) or 2 (about 9 mph) and use the gears to adjust my exertion level. One thing I am not thrilled with on the Flow is there's no indication on the display what gear I'm in. I've adjusted to that, but it would have been a nice feature, like on the La Free.
The balance on the Flow is better than the La Free because the battery is in the down tube rather than under the rear rack. Most of the time it's not an issue, but tight turns and having to stop on a hill feel better on the Flow.
With the La Free, I always have to remember to gear down when coming to a stop or before starting up a hill. With the Flow, I've got a throttle, so don't have to worry about starting from a stop or heading a hill in any gear. That comes in pretty handy!
I had my La Free about a year and a half before I bought the Flow. I like both bikes, but they are different, and different to ride. If I were buying now, and IF I knew the Flow could handle the hills around my West coast home, and I had the same budget, I'd probably get the Flow. The La Free has increased in price, and, while I like the more natural riding feel of the La Free, the more stable feel of the Flow, along with the throttle and the price, would be in Espin's favor.
I do have a Giant LBS in town, but any electrical work would go to the "big" store an hour away. I've also got an REI 20 more minutes up the road that would service the Flow, so having dealer support close by isn't a huge difference to me.
