Complete Drive Set — Controller + 750S Display + 750W Rear Hub Motor
Controller, display and motor out of the same system. The three parts were built to work together, so the parameters already agree — pole count, hall geometry, wheel size, current limit. Nothing to teach the controller, nothing to guess at.
Buying a controller alone and hoping it drives the motor you already have is where most e-bike repairs go sideways. A factory controller is potted and its parameters are locked; it cannot be re-taught another motor. If your motor is also suspect — or if you simply do not want to gamble — this is the set that removes the question.
In the box
- 48V 750W sine-wave controller — 12-MOSFET, 22A ±0.5A, potted, XT90 battery lead
- 750S grayscale display — Julet 5-pin, Ø31.8 mm center clamp, separate 3-button pad
- 750W rear hub motor — brushless geared, 48V, for 26″×4.0 fat-tire builds
- All three matched as one set before packing
It is the motor body with its axle and cable — not a built wheel. Someone has to lace it into your rim and true the wheel, or build a new one around it. If you are a shop, that is routine. If you are a rider working in a garage, budget for a wheel build at a local shop before you buy this set.
Fits
Built for the 26″×4.0 builds these three parts came out of — R1 and Pegasus. On those bikes this is a like-for-like rebuild of the entire drive. On any other bike, email us first: a complete set removes the controller-to-motor question, but the frame, dropouts and wiring still have to accept it — and the controller’s parameters are locked at the factory either way.
- 26″×4.0 fat-tire e-bikes running a 48V battery and a rear hub motor
- Standard fat-tire rear dropout spacing — measure yours before ordering (135 mm, 170 mm and 190 mm are not interchangeable)
- Cadence (PAS) and throttle systems
Not for
- Closed CAN-bus systems — Bosch, Shimano STEPS, Yamaha, Specialized, Trek, VanMoof
- Torque-sensor bikes where you want to keep the torque feel
- 36V or 52V packs — 48V only
- Riders who need it working this weekend without a wheel build
Send us four photos first
Email support@riderow.com: the battery label, the old controller with its wires in frame, the display on the bar, and the rear dropout with a tape measure across it. We will confirm the fit — or tell you it is not the right set — usually the same day.
What is not included
Battery, rim, spokes, tire, throttle, brake levers and PAS sensor. Keep your originals or ask us what plugs in.
Warranty: 1 year on all three parts, serial-tracked from the day it ships.
How we work: RideRow sells parts and the information to install them. We do not run a repair shop, take bikes in, or do house calls.
