Hi Ken I have a Model 30 Moda which on the whole has been great, getting on for a year old now, I use it to commute around London. It does sometimes struggle a bit with inclines, and also struggles to get above 24 or 25mph. Is there anyway I can get a few more MPH out of it? Range wise I would say its good for 25 miles at the moment, the power seems to be fading further with the decline in temperature as per other posts.
