ST2 Magura Upgrade

Talked to the product team at Magura at Interbike. They indicated that the MT5E brake system will be available as an upgrade to the MT2/4 brakes on the ST1/ST2 and should be shipping soon. The system comes with a motor cut-off sensor that simply plugs into the existing cable (on the handlebar). I think he said approx. $130 a side (retail price). Nice upgrade option for those wanting a 4-piston brake.

I believe the St2S has the MT5 system in place.
 
Upgrades are always a nice option! Indeed the ST2s does.

Are those anti- lock? 260 for 4 piston calipers on a 28 mph bicycle? If they are anti lock, I apologize. If not, then it would be a total waste

@fxr3, Stromer is making the suggestion, not 86 and still kicking. That price per side is not unusual for better quality hydraulic brakes; we've retrofitted a number of heavier ebikes with various brands and the price for intro type starts at about $110 and goes up. Better quality, higher performance brakes cost more. Here's what Magura, the brake system manufacturer had to say about its new system:

MT5e for E-Bikes and S-Pedelecs
FOUR-PISTON BRAKING POWER, NOW ALSO FOR E-BIKES!

The number one upgrade for e-bikes and speed pedelecs is targeting the booming market for e-bikes and speed pedelecs, which have power assistance up to 45 km/h, with the new MT5e.

Demanding All-Mountain and Enduro mountain bikers have already been convinced by the benefits, and these are just as important in traffic: the lightweight brake lever housing, made from MAGURA-exclusive Carbotecture material, offers superb ergonomics when combined with the special pedelec brake lever in die-cast aluminium. The ultra-rigid four-piston brake calliper, with easy brake pad replacement thanks to magnetiXchange pistons, provides superior braking power in any conceivable riding situation. And the legendary MAGURA Royal Blood fluid is not just more environmentally friendly than the DOT brake fluids used by many competitors, it also guarantees long-term low maintenance and therefore low cost of ownership.

MAGURA have come up with a groundbreaking new solution for the MT5e: a mechanical switch located right inside the brake lever. It activates the brake light even before the brakes actually bite, and this will also be useful for power assist systems with a regenerative braking mode, so that it can be engaged as quickly as possible. And should a crash occur, exchanging the unit is much cheaper than with our competitors, because the switch is located within the brake lever housing.”

The MT5e also uses the new Storm HC brake rotors. Compared to the previous Storm models these have even higher stability under load and greater mechanical strength. The new friction surface geometry of the brake discs, which are still 2 mm thick and available from 160 to 203 mm in diameter, provides optimum wear and noise performance.

The new MAGURA MT5e will be available from Autumn 2015 – and by then it will also be factory-fitted to numerous e-bikes and speed pedelecs.
 
So Ann m, magura, you, and or Stromer are suggesting my 7000 st2 does not have adequate brakes? My st2 may not have a top notch bell, but the brakes are awesome and more than enough to stop that 28 mph bike. Anti lock would be a benefit, 4 piston would be a bit much pushing on brake pucks that are half the size of a matchbook. Antilock dual front discs would at least not get a "foul" rating from me.
Otherwise "bling or upgrade" would be a diplomatic way of saying what I just said.
As far as the Magura quotes- well their business is selling brakes- so might be biased.
 
I don't blame Stromer. As an expensive brand bling is part of the expectation for a lot of customers. My comment was because my stock Margura's are the best bike brakes I've experienced. And I've been riding a long time. LOL
 
Marketing and Sales will be disappointed - but I have to say it.

On a road bicycle, all hydraulic disk brakes do their job. The absolute limiting factor for the braking distance is the tiny surface made of rubber which makes the contact between the road and the bicycle!

Riding a mountain bike in a long and difficult downhill section will force you to use the brakes until the front disk is almost glowing. Then, you're lucky having the most heat resistant brakes. With a road bicycle, sucht intense use of the brakes is unlikely. Additionally, the ST2 & ST2 s have a outstanding motor brake system. For the most situations, you even don't need the mechanical brake.

The ST2 s is the top model, that's why it's fitted with top equipment. With the same reason, you could change the handlebar or the seatpost into a carbon part.
 
Also a 1st for me, was experiencing what felt like zero slippage between the pads and rotors while braking in heavy rain with my St2 fitted with the Magura brakes it came with.
 
I haven't had much experience with disk brakes. My tektro brakes on the Neo Carbon were stronger (had greater bite with the same amount of lever pressure than the Magura's I currently use. I am not sure if this is do to the mechanics of the braking systems or the weight disparity between the two bikes. I have a couple of downhills in my area where I break the 30mph barrier and for me, a 4-piston caliper should, theoretically, provide greater stopping power. I tend to error on the side of greater envelopes of safety which is why I have supplemented the existing lighting system with a Light and Motion headlamp and tail lamp.

In the automotive world, I have upgraded my automobiles with aftermarket performance brakes and I can tell you unequivocally that they work much better than the oem equipment.
