http://electricbikereview.com/daymak/ec1/ The Daymak EC1 is a carbon fiber electric bike available in three flavors: Standard, Advance and Pro ranging from $1,899 to $3,499. A light weight, value priced carbon fiber electric bike available in three flavors: Standard, Advance and Pro with larger batteries and more carbon parts on the higher models (including drop bars on the pro!). More modest 250 watt planetary geared hub motor drives all three models, paired with the wider 700c wheelset this motor is on the weaker side but also weighs less, it’s a “active” setup. Delivers five levels of pedal assist and a trigger throttle with override so you can pass fellow riders or top hills without changing gears (though it does have 21 gears which is nice). Value level components including Shimano Tourney TX derailleur, extra shipping charges for the US, only one frame size ~22 inch, decent one year warranty on frame but only 6 month on the battery and motor.
