Oh. I'm very careful riding in Cambodia. Have been riding my bicycle the past few years so I'm used to the traffic, and SR is way quieter than PP so that helps too. In any case, if I have Ruby in front I'll have to be even more careful with no sudden starts or stops where she could lose her balance. I'd be devastated if anything happened to her remaining front leg.
Specs on this model are a bit thin, but it can apparently travel 80km on its 60V 20Ah battery. But with lead acid batteries you really should avoid discharging them more than 50% otherwise you'll reduce their lifespan until it completely drops of a cliff.
Had a go trying to get Ruby to hop on yesterday but she wasn't interested even with tasty treats on offer. Once she catches on she'll be fine. She doesn't have to be told to hop in a tuk tuk with me, so there's hope.
