ABSOLUTELY LOVE MY V10F!! Took 30-40 minutes to get the hang of it. 2 hours to start riding it the park and the bike lane in downtown. It took 2 days to comfortably start with no wall, this one is a bit tricky. 2 weeks now and I keep the speed unlocked at a comfortable 34kph. I've tried the max 40kph with safety gear, but it is too fast for safety in downtown, or in general I'd say. When the speed clamps hit at max 40kph, I almost lost balance and flipped over. Be careful and wear safety gear when going over 25kph! My V10F has become my main transportation in downtown where it is bikers paradise. It is the best experience to feel the wind rushing through your face on a sunny day out. The only hardahip I had so far is that it's incredibly hard to ride holding unbalanced grocery bags in one or both hands (obviously). It's a challenge to balance in general, but if you can manage to get started just hold the bags in middle for balance. If this will become your standard method for groceries, get a backpack for sure. I've been talking about getting one of these for years. It's time I finally got one, and it was all the worth while.
