Hi everyone, this is my first post. Way back in the beginning (sort of) of the eBike, there was the Currie US-Pro Drive (USPD) circa 1999. Being a gadget-guy, I was intrigued. I had a Trek 820 aluminum mountain bike with decent (for the time) specs. A 28 pound, 24 speed entry level bike, that was really fun to ride. I bought the USPD, and discovered that my spoke pattern didn't match, so I bought a new rear wheel with the proper spoke pattern, thinking I could switch out back wheels to get the bike totally back to stock if I wanted. The system used a 350 watt (rated), MAC motor with a secondary chain. SLA 24V 12AH battery pack was heavy, but lithium wasn't around then. The bike was a blast to ride, and served me well for a few years.
Then, in 2003, I got a MRSA bone infection, was in the hospital for a month, had a hip replacement and parked the bike. I pulled it out two weeks ago, removed the battery pack, and got the bike road worthy for pedal only (with the MAC-Can still attached). First ride was 3.4 miles, and I did 7.5 miles the following week. Not bad for a 50 year old @ 6'2" and about 220, and not having been on a bicycle for over a decade.
My replacement SLA batteries should arrive today ($50 total cost), and I shall see if the old USPD still works. I inquired on ES about upgrading to a 24v 10ah water-bottle style lithium pack (around $200 from golden motor), but someone posted that the new technology would make it sorta dumb to put any more money into the old Trek/USPD system. So now, I'm drooling over the iZip Dash, but can't justify the expense in my mind.....
Please help... (tongue planted firmly in cheek)
