Re: New E-Bike Conversion - 26" vs 29"

I think you're mixing up the bike jargon. Fork length doesn't matter. The point of contact is the dropout (gap where the wheel goes into the fork). putting a hub motor in will put forces on the dropout that it wasn't designed to handle (the torque is big and the point of contact is small) which is w...

Re: New E-Bike Conversion - 26" vs 29"

Theres more torque because the distance is longer. Think how a breaker bar works and the only thing holding it in is an open ended aluminium plate. Thats why you need a torque arm.

Re: Coming back to the Ebike sport.

Where in Melb are you located? You can test some of the custom bikes that the shops around here build (Ballarat e Bikes/Frankencycle etc). I believe Ballarat e-bikes will build a custom frame for full integration as well. Even with regular cells, you still need to balance them up front the same as L...

Re: New E-Bike Conversion - 26" vs 29"

FYI : the 29er wheel from EM3EV is the 700c rim with Alex DM24 Disc. I was one of the first to get it and got it laced from them with Sapim Spokes (should have gone black instead of silver). If you get it laced from him, make sure you tighten the spokes before use. Theres usually 3-4 that get loose ...

Re: Anyone here use a MAC 500/100 watt motor on a Road Bi

I run an Alex DM24 for balloon tires. I think the only other one designed for ebikes in 700c was DH19.

Anyways, good luck with your build. =)

Re: New E-Bike Conversion - 26" vs 29"

I disagree. 26" is more appropriate for ebikes maybe 1-2 years ago, but for a commuter (road/park/light duty bush) a 29er is more suitable with a geared hub motor. It's just the difference in manoeuvrability between wheel sizes and what you're comfortable riding at the end of the day. As a commuter,...

Re: Anyone here use a MAC 500/100 watt motor on a Road Bi

If you've got disc brakes then I say go for it. Just don't go overboard on your first few trips as you'll be smashing 60+km/h and it's easy to be addicted to speed and overtaking pretty much everything that isn't a car or motorbike. I run a MAC10T @ 48V (58V off the charger) and hit 50km/h, so a 6T ...

Re: Anyone here use a MAC 500/100 watt motor on a Road Bi

I cant comment on the MAC 6T, however my MAC 10T will shred aluminium dropouts pretty easily without torque arms (58V 14S lipo + 12FET 40A) . The bigger issue is brakes and tires as you're going faster than normal road bikes and the bike is an extra 8kg heavier. I personally wouldnt go faster than 3...

Map your route in mapmyride or any other elevation chart so you can actually see the real elevation to make sure it's actually 20%. (which is quite steep). The correlation for amps and volts is : More volts = higher speed. More amps = more pushing force. If the road is flat, you wont need much pushi...

Re: Controller Power issue

I'd suggest a 14S extension cable and modify it to split the packs into - 5S, 5S, 4S. OR 7S, 7S so you can use cheaper parts to revive the low batteries. A 14S balancer is expensive. A 6S balancer is cheap. A 6S battery medic is even cheaper. Either way, once you have the balance wire splitter, you ...

I assume you're getting a MAC 12T kit from em3ev since you mention "12 T"... Personally I'd jump to a 12 FET 40A controller for the 15% hills. I also think you could get away with a 10T (what I run) as it climbs hills like a champ. I'm not a lightweight either (sitting at about 200b). This is me on ...

It looks the same as a generic XML-T6 housing. In which case it means the housing is aluminium and can easily be drilled out (remove the light fitting first) and you can mount a bolt to it.

Re: Very short commute, bike stored outside

For such a short commute, you can stick everything in a large saddle bag and charge at work if you needed to. Just convert the motor plugs to andersons or something and tuck it under the seat for easy disconnect. This is pretty big 12FET 40A controller... You could probably get away with something s...

Re: Single Speed Conversion

I find 46T front and 11T rear not enough for pedalling at 30mph on a 29er/700c ( i like to pedal as well ). I don't touch the front derailleur but run through my 9 speed rear a lot. During my commute I punch it off the line pretty hard - using MTB pedals and heaps of gears to cycle through. My gear ...

Odd, I've bought 6-7 of those WE throttle and none of 'em exhibited any stickiness. In fact, I like them because they don't stick and the spring isn't as strong as some others I've bought off eBay. Are you sure the grips aren't shoved into the throttle causing it to stick? Yeah, I read other favora...

Most people suggest a hub motor because the chances of f*ck up are less and you don't need any special tools as long as you get a complete kit. It's literally : - screw on the side panels of the motor. (if you bought an already laced kit) - Bolt brake disc to hub. - Strap on the freewheel. (twists o...

Im pretty happy with my MAC10T geared hub at 58v (14S Lipo). Do some reading on DD vs geared hub to make sure you know what you want in a hub.
