Harry i don't have a ebike but I have been studying e-assist kits for a Catrike recumbent trike. The recumbent shop where I bought my trike loves the Bionx and has more than he wished he had in stock=expensive paper weights. Falco looks like it would perform similar to the Bionx but the battery isn't proprietary, but they site states the five year warranty is void if you don't use their battery. Falco seems to appeal to the same market as Bionx. My concern is from reading various internet comments, for whatever that is worth, your credit card is charged at the time of purchase and a number of purchasers have experienced several months of delay before delivery. Sometimes all the parts are not in the delivery and it has taken more time to get everything. Utah Trikes recommends the wired display, not the wireless as they experienced problems with the wireless. I've read a couple of complains of controller over-heating but don't know if this is generally a problem or not. The up side is that it is highly programmable, check out Youtube videos, can run up to 28 mph, and has a good torque sensor which is a high priority for me. The down side is I suspect (I am just guessing) Falco is under capitalized and they use current cash coming in on new orders to complete and ship older orders. Additionally the owner is an electrical engineer, the product may be good or not, but I bet engineers are running the company and not someone with business experience. My "guess" is Falco will go the way of Bionx. I like what their website says about the product and apparently how it operates but I don't want to spend $2,200 for a Bionx like paper weight!
