There has been so much progress with electric motors and high capacity batteries finally reaching widespread use. There are kayaks with an electrict support (Torqeed<\/a>\u00a0here in Starnberg, that I wished to have one \u00a0yesterday at Ammersee). There are engines for ultralight planes like the Electraflyer<\/a> while I just read at science.slashdot<\/a> about an electric airplance.<\/p>\n

The most fascinating piece, however, I have seen last Sunday at bike expo here in Munich is \u00a0a 1200 Watt kit that can be mounted on most frames of current MTBs. Tthat’s a lot of savings compared to buying a custom built e-bike<\/a> like the KTM eGnition, Elmoto, eRockit, Grace or eSpire that all come at weights of 25-35 kg.<\/p>\n

The kit will be sold by the next month by ego-kits.com<\/a> while here are two pictures from the Munich fair.<\/p>\n

The performance data are quite impressive:<\/p>\n

1000 m of vertical climbing (3280 ft.)
\n70 km\/h vmax (43 mph) without speed limiter
\nUp to 40 km travel (25 miles)
\n1.5h charging time
\nmasters up to 80% incline with practice (!)
\nnominal power 1200 W, 2500 W maximum
\nmotor weight 3.2 kg (7.05 lbs), with battery in backpack about 5.5 kg (12.12 lbs)<\/p><\/blockquote>\n

I like the central and downsize position of the motor with low center of gravity. There is also no force to the suspension. While I expect some heavy war off on chain \/ sprocket, this needs to be tested in long-term experiments. So far, the combination with a Rohloff Speedhub hasn’t been tested while I don’t see any problem as this is been in use by the eSpire<\/a>\u00a0for some time. Sound emission seems to acceptable but expect no silent move.<\/p>\n

Unfortunately, the ego kit aren’t allowed on German streets, but that may change in the next year. At least the auto lobby already launched reports how dangerous electric bicycles<\/a> are …<\/p>\n\n
