We are visiting Vancouver on a regular base out of home country the Netherlands. Back home The wife and I ride an e-bike manufactured by Sparta having a frontwheel drive. In 2014 We bought a Chinese manufactured eWind bikes at a local shop here in Vancouver to make our rides in the area less demanding. About two years ago I have replaced the battery and notwithstanding the low workmanship the bike at a cost of C$ 1299 performed well during the few weeks a year I am using it.
Just recently one bike gives me a problem which I don't know yet how to resolve, during normal cycling it may suddenly stop to assist further suport. Display blanks and I have to restart to regain support..
Some details:
Controller is DAPU 36JK2TT1403A727, it has a 9 pin connector to the drivemotor
Motor is HLGE236V261400183
Display is LCDHTT1306A641 (36V)
Battery is Li-Ion 36V, 10 Ah it has ON/OFF key and 4 LED status panel
There is a PAS installed as well as a one position only throttle
The abnormal indications I see on my display during normal assisted ride are:
The battery level reads low (1-2 bars) and may return to FULL after a while, same as LED on battery it self.
The speed indicator is allways reading 0.0km/hr
The Pedal Assist Level indicator is oscillating from nil to full, even at standstill of the bike
When powerloss occurs, display is totaly blank.
My first approach to troubleshooting was to suspect an intermittent contact from battery mainsocket, I tried bumpy roads, speedbumps, letting rear wheel drop to ground but there is no relation to the problem.
I opened up the compartment housing the controller to discover a Chinese Mash of wiring, but no signs of overheating or poor contacts. Tried to duplicate the problem of loosing display by pulling wires and connectors. No result.
Also swapping batteries did not do any help, (my battery does fine in wife's bike)
Question:
Any recommendation to replace which parts for reasonable cost?, unfortunately the original bike vendor is no longer in bussiness....please note pictorials are not my bikes but very similar...
