Re: Ultimate stealth ebike 30 mph

Cool idea! One advice for those cheap chinese motors is use 3 very strong cable ties just above the spring that protects the motor wires at dropout zone, because the spring invariably moves away from the bend unless there are cable ties holding it there. I feel lucky to be in a European country whe...

Re: 5 k miles check up.

1200 watts peak. Actually. The cheap torque arm does have a pretty tight fit on there now that you mention it.

Re: Vector Typhoon Frame / QS 205 / 20s15p 30Q / Nucular 24F

Yeah but if a cop sees that whizzing by won't he just think it's an illegal dirt bike? Maybe not a problem where you live, apparently not a problem here too because I've seen ghetto dudes ride dirt bikes around the city and cops don't care.

How many amps is your battery and the volts?

Re: 5 k miles check up.

Yeah it's gotta be something like 2000 watts when I'm pedaling full burst on this thing. I'm pretty strong and with the high gearing I can really pedal hard especially with the throttle full blast. Also I don't know if you can guys can see but the dereilleur hanger IS steel and if you look at the pi...

Re: 5 k miles check up.

Also depending on how aluminum is designed it CAN be good. Case in point the JANDD expedition touring rack vs the TUBUS stainless steel rack. The JANDD rack uses reinforcement in the rack, i. E. Aluminum rod cores inside the rack struts. That way if it cracks the struts still have support. I cracked...

Re: 5 k miles check up.

The grin v3 looks great. I like how it mounts to an eyelet. Problem is that you still should put a tac instead of bolting the two pieces together. That way if the drops snap the wheel stays in

Also, Ive got to get the giant molex hall effect sensor though the middle of the arm. Not going to be easy

Re: 5 k miles check up.

Also 99 good point about the weight of the rack over the drops. I guess that's why a bunch of guys use midtube packs. So all that weight hits the drops harder too. Damn. But in the scenario the drops snap off completely like I have seen in some other members posts, what then keeps the wheel in place...

I contacted Chinese manufacturing (Voilamart) and they told me I don't need torque arms at all. It's so low low torque this motor. It's...

Re: Ultimate stealth ebike 30 mph

The bags cost $300. Most other ebikers build the battery mid tube. But that just kind of stands out to me, though I can see WHY. I'VE BEEN snapping racks because of the weight and speed. 50 lbs of cargo going 30 mph... I also stripped the upper bosses where the rack arms attach. Next thing I guess i...

5 k miles check up.

Hi. I've been riding for about 5 thousand miles on an aluminum frame. I'm wondering about the health of the drop outs because I run a 1000 watt motor. I also pedal a lot so I have an extra 250 - 500 watts coming though. I have a massive front chain ring and very small gearing in the back. Usually 55...

Re: Ruined $150 Shimano Deore hydraulic brakes

I guess it's worth a try to buy that dual pull lever and hook up both a rim and a disc brake up front. No use speculating about how it works or if it creates DOUBLE (2X) braking power. I like those sunlight levers because there's a mechanism inside that helps get your cable pull ratios exact. so I'l...

Re: Ruined $150 Shimano Deore hydraulic brakes

Not long, but it's enough to really accelerate at a stop light. Especially with the electric assist. It also has the benefit of making you more stealthy. Like "hey officer im just fast!" :lol coming straight on, people just look at your pedals most of the time. It's eye catching. I hardly ...

Re: Ruined $150 Shimano Deore hydraulic brakes

Everyone has their own preferred style of braking power, limits, threshold because everyone has their own way of riding and the terrain and speeds are so varied.

Re: Ruined $150 Shimano Deore hydraulic brakes

You can only deliver enough power to lock up the wheel. The great thing about the hydraulics is that you can dial in the bite point. I those deores sometimes the brakes would bite too hard and the wheels would lock up. A wondering bite point. Sure a disc rim brake combo on the front would lock up.th...

Re: Ruined $150 Shimano Deore hydraulic brakes

If one was to actually install a disc and rim brake on the same wheel, there would be some obstacles to overcome (assuming you wanted to actuate both brakes with the same lever). To make the brakes grip roughly the same (ie not one just one doing the work and the other making no contact) you'd have ...

Re: Ruined $150 Shimano Deore hydraulic brakes

frock. Just went to a bike shop. Dude didn't know what the hell was going on with the rear brake either. Tried to cut my brake line with a pair of regular wire cutters. Nope. Nope.
