It sounds like you have been bitten by the cycling bug! And with a Brompton in your thoughts, why not experience the world on two small wheels and do rolling just for fun rides? Sometimes when things don't work out as planned, there's an eventual purpose that supersede it. Who knows what kind of journey fate has for those passionate about something, all we need is place more emphasis on having fun and doing what we love- because loving that process just keeps us going. And maybe one day ebike technology will catch up to your high demands too!
