The 9D is the perfect geometry for my ailing back
With my second L5-S1 back surgery behind me in February, I needed cargo-capacity eBike whose geometry would keep my back relatively straight. The 9D Benno RemiDemi fits me perfectly and I am looking forward to years of carbon-avoided commuting without even breaking a sweat :-)
great e bike
This is an amazing bike. It's a pleasure to ride to and from work.
