Magnum R2 Conversion Kit Review – $1.1k

Magnum R2 Conversion Kit Review – $1.1k The Magnum R2 Conversion Kit is a versatile electric bike conversion kit with a ton of features, priced at $1,099, comes in multiple wheel sizes so you can make most any conventional bike into a rear hub motor ebike. A complete kit with battery, geared rear hub motor, functional rear rack that holds the battery, wheel rim, cadence sensor for pedal assist, mechanical disc brake levers with motor inhibitors, display, controls, and throttle. The rear hub motor is fun and responsive with 90nm of torque, 500-700 watts, throttle, 48v 13ah battery, and cadence based pedal assist via the 12 magnet cadence sensor. Will take time and effort to install, can produce frame flex, makes bike heavier, and can look home-made if details are left undone.

  1. I do builds with mid drives and with a big battery like that I stopped putting them in the rear rack because of the frame wobbling.

  2. The battery on this Ebike Exceeds FAA specifications. of 160 watt hours. According to the website this battery is 187 watt hours.

  3. Your attention to detail is incredible, nice review

  4. Thank you for the reviews I am trying to reach Raleigh corporation regarding my battery Is dead and you cannot do it nobody in the corporation maybe you have their phone number

    It’s a shame that rack batteries get such a bad rap. On Townie style frames with longer wheel bases there’s absolutely no feeling of rear heavy or tipsiness. Also I wonder if the latest versions don’t address the wiring issue. I was certain I was told they were Higo connectors…. Guess I better talk to Chris.

  9. I’m looking for a simple kit with up to 500w front hub motor, a smaller bottle-mounted battery and a throttle. I don’t want sensors, screens or button pads, is there something like that out there?

  10. For $100 less you get a whole bike, already built and a lot more versatile. the Lectric XP

  11. If a company doesn’t want to pay your universal fee then no review on this channel right? So there could be some really good bikes not getting on your channel.
