New Geared Hub Motor Kits
Throughout the year we have been sampling hub motors from a variety of different manufacturers aside from Crystalyte in an effort to continue offering the latest and best electric bicycle conversion parts. One of motors that stood well apart from the pack is a new 400 watt geared hub motor from the eZee bike company. Our first large shipment arrived last week and the system is available now as part of a complete kit package with a 37V 10Ah lithium battery pack.
Custom 50A Motor Controllers
Let mosfet failures in 72V Crystalyte controllers be a thing of the past! We sent Crystalyte a batch of IRFB4110 mosfets to incorporate into a custom run of 72V motor controllers capable of 40A and even 50A current levels. These mosfet transistors have 1/3rd the ON resistance of the original 4710's used in previous 72V controllers and so are far more tolerant of the large motor currents in high voltage setups. As well, the stock 72V controllers now use IRFB4310 mosfets, which have over 40% less internal resistance than the original transistors.
January Update - The modified 72V controllers sold out in no time. Our next batch isn't due to arrive until March as well. However, the stock 72V 40A controllers with the IRFB4310 mosfets have been holding up just fine with most 72V arrangements, so unless you really need 50 amps, then the standard 72V controller should be fine. We have modified the Low Voltage Cutout on these to 27V, and have also added a waterproof conformal coating to the circuitboards as well.
