Ebike bling

August 16, 2010

My foot is almost fully recovered now and thanks to everyone for their good wishes.

I’m back on the mundo and really enjoying some early spring weather cruising around Sydney. The Mundo is great to ride again. It really is just as good a ride as my other hub motor bike even with the extra weight. I broke another chain and in the process snapped my derailleur but I think I’ve finally worked out what I was doing wrong with the chain joining thing.

I have recently got some great pics from a fellow ebiker, Mark, with a greenwheels, very bling. These picture just go to show how these bikes can make efficient and stylish transport if your willing to keep them maintained and update the more dodgey parts. Here’s the pics of his bike

Below is my greenewheels with a new ping 15ah battery in the rear basket. It is working great and while it seems to feel a little torquer on takeoff it has the same or a little lower top speed (28kph on the flat no pedaling) as with the previous battery and controller. Now I just need the motivation and time to mount the battery more permanently so I can give my wife back her makeup travel bag!

I’m also going to repost a response Mark gave me to a previous post as I’m sure there are others out there with these greenewheels bikes who want some help in keeping them going

“..So my Bafang motor lasted 2700km before failing, which was better than the 13Ah greenewheels battery, which only lasted about half that before the BMS fried itself, thanks to you I managed to fix that with the BMS in your your dud GW battery with the cactus cells. Thanks again for that and the spare charger, it’s coming in very handy.

In any case ordered some honeywell SS411 hall effect sensors from Farnell and some 1.6mm heatshrink, on monday morning, arrived at work tuesday morning. farnell have free shipping for any order(might be sydney only), which is amazing as the two sensors and the heatshrink only added up to about $10 which is the min credit card limit.

Did the open heart surgery on the Bafang last night and hey presto, it’s working fine again. The original hall sensors don’t appear to be any good, as seems to be a common failure if you look at the endless sphere forums.

Have also just taken delivery of a whole stack of upgrade parts from ChainReactionCycles from the UK, so cheap with the strong dollar. Got a new disc only Halo Freedom Disc 26 front wheel, a shimano XT M775 hydraulic brake and 160 rotor, plus new wider Easton bars and stem, (original bars a bit narrow for me at 585mm new ones 684mm) plus some continental city contact 1.75 tyres. Also have recently upgraded the extremely woeful original bottom bracket to a shimano cartridge one and some new campy cranks and 53T chainwheel, and new 13 to 34T freewheel cluster, (original 14 to 28T) so pedalling is much nicer and easier to cruise at low cadence, plus can spin to 55km/h down the hills on the way home from work each day.

The new headlight I put on the beast is amazing as well, It’s a VisionX Solstice Solo S1102 15° beam, 50,000hr 10W LED, 900 lumens, as powerful as a 100W halogen, runs from 9 to 50v so a perfect fit for the 36 to 42V of the onboard power.

So these bikes are great but only if you are willing and able to patch up, repair and modify due to quality issues. I would not recommend them to anyone who is not a DIY type. I note that Shimano are releasing electric bike kit in the 4th quarter this year, ‘Shimano Steps’ it’s called, no doubt will be more reliable than this gear.”
