Did a spin to practice pre-GVBR last day, and Thing1 thought it would be a good idea to show her mother the new ByK (above). Which she did.
Then, when my back was turned, she was test-riding this!ByK E500x16
. The twist grip was a little tough on her - she could change up, but not back down. She didn't try the FD, and I'd be surprised if she could manage that at all (not that she'd need to for some time yet, really. I could always change cogs for her pre big hill. It's SRAM X4, so I'm guessing shimano pull ratios so one could potentially put triggers on it if it came to it? Guards and rear rack available too.
She loved it (even though a smidge big). In fact, she loved it HEAPS! Quick. Stable. Light. So, it's safe to say, if she was getting a new bike for her 7th birthday next Feb, she'd be getting one of these. But she isn't, so she won't.
