This is a low-speed e-motorcycle pretending to be an ebike, some cops are taking issue with this.
It is also very heavy 180 lbs. Pedaling these devices is next to impossible.
This has been my impression as well. Being a driver myself I know how annoying is to drag behind a small gas powered moped struggling in 30 mph zone, and Vienna can only do 20 mph.Daymak tends to sell lower cost mopeds and ebikes that don't tend to be good transportation-grade solutions.
I don't know what ebike you have previously own but I found that the industry has pretty much focused on selling the EU compliant models in the US which I just feel lack the performance to be true transportation-grade products. A few ebike branks like Frey and FLX have ebikes that are close to being great commuting ebikes but still seem to be products designed by cyclists for cyclists.
I think the only way to know what is needed for an ebike to be an effecting commuting solution you have to have ridden seriously for a few months.
I bought the lithium ion battery and am changing it for the spa. This should increase range and speed?
Speed depends on motor and controller, not on whether the battery is lithium or SLA.
Range depends on the battery WH rating - and on the speed too. The slower you go the farther you'll get. They claim 40 miles range on Vienna but I doubt it will get that far at 20 mph speed in real life conditions.
