I've put two ebike conversions on LWB recumbents, one Fold Rush and one EZ Sport. Used front wheel hub motors in both, one an EZEE kit from Grin Cyclery and the other a kit from bmsbattery, shipped directly from China. They are both still going but we did have to replace the bottle battery purchased from bmsbattery. The Ezee 14AH 36V battery is still going strong after 5 years, but then it did cost at least 3 times what the bmsbattery cost. Having the weight of the motor in front seems to work nicely on the LWBs, which sometimes get a little light in the front end when going uphill, especially on dirt.
