  1. eCVT is 100% gear based and has no reciprocating parts, no friction, no shifting mechanism and is simpler, more efficient and reliable than a manual/dct/automatic and can handle high torque. its perfectly balanced, doesnt need ratcheting, and also eliminates/replaces clutch, starter and alternator. it is just a single planetary gearset as found in most modern automatic transmissions (except they use 3/4 of them) that has one input shaft connected to an engine (or pedals im case of an ebike) , a second input shaft connnected to an electric motor, and an output shaft connected to the driveshaft/axle. it can be driven by either the engine/pedals , or the electric motor, or combination of both, and the electric motor controls the gear ratio. there is no slippage and the ecvt runs in transmision oil that requires virtually no maintenance. its used by toyota and ford hybrids and toyota has made their patent free of charge.

  2. ​ @DonziGT230 I don't know about ford but the Toyota eCVT that are based on the same principle are very reliable, and they are more efficient than either a manual or automatic because they have less moving parts.

  3. eCVT is actually simpler than any other transmission. basically one planetary gearset (one sun gear, 3 planetary gears and one ring gear) and an electric motor and together they replace the gears, clutch, starter, alternator, shifting mechanism etc. the electric motor is doing the job of varying the gear ratio plus adding or recuperating torque from Regen.
