Nine Continent RH205c type S rear motor kit, without battery. The listing describes a symmetrical offset design and components offered as mutually compatible.
Advertised contents: a choice of RH205cS motor on an included rim, a freewheel supplied already fitted and a choice of accessory pack. The motors are stated to support up to 2000W; the accessory pack determines final power.
Each pack includes a cycle computer, a brushless controller accepting 36V, 48V and 60V, and a multivoltage thumb throttle. Computer functions include power on/off, speed, total and trip distance, battery level, assistance power, five assistance levels and cruise control. It can be configured for 36V, 48V or 60V batteries.
Motor choices: RH205S 9x7 330/420, very fast with torque for some hills; RH205S 10x6 350/480, focused on speed and long distances and to be avoided in mountains. Higher torque in Nm favours climbing at the expense of speed in rpm.
Advertised examples with a 48V battery measured at 165 rpm, approximately 25 km/h according to this listing: 9x07 RH205S-330/420, 36Nm; 10x6 RH205S-350/480, 30Nm. Rpm means revolutions per minute and Nm newton-metre. Speeds are indicative and vary with the battery.
The kits exceed the 250W power stated by the listing for electrically assisted bicycles on public roads: the listing restricts them to private roads. Build examples and component links are retained below.
Half-twist throttle: historical reference, ask the shop to confirm availability and compatibility
