Vectrix charge delay

DovG — Sun, 01 Nov 2009 19:33:04 +0000

Received my 2008 Vectrix VX-1 last week, with 397 km. Tried unsuccessfully to display or to set the pre-charge delay. Followed the additional instruction booklet supplied with the Vectrix, (Reference NBTB0814, Rev. 1, 30Oct08). The batteries are depleted at this time, I wish to find out the delay setting and modify it to my needs if necessary.

Heinzmann motor repair

Mspector — Sat, 24 Oct 2009 17:02:33 +0000

I have a Heinzmann 36v 500watt e bike. I have replaced the batteries but my range of use is still not what it used to be. I think the problem may be in the rear hub motor. Any suggestion on how I may procede to resolve this problem?
