2017 BH Easy Motion Lineup

Easy Motion has made some dramatic changes to their lineup for 2017. As has been the case in past years, Europe has the lineup first. Appropriate given BH is a family business, headquartered in Spain.

New bigger batteries really caught my eye, 400, 500 and 600 watt hour, using higher power cells. The display for at least the hub driven bikes has been redesigned and moved to the center of the bars. It's still removable but this should resolve the problem some of us have had with those tiny contact pins, losing contact. I really like some of the new colors as well. So many mid-drives! BH has some of the best looking, best equipped ebikes on the market, and 2017 is no exception.

Happy shopping!

That's awesome news! We need more ebikes with 600Wh+ batteries!

It appears they still have some typos on their website that they need to fix. For instance, I found that in some places, they quoted battery capacity in watts instead of watt-hours, and on one sliding graphic, they said they were using 4.2Ah battery cells in their batteries which is quite odd because the highest-capacity commercial cells are 3.5Ah (perhaps they meant 4.2V instead of 4.2Ah?).

For the love of God please bring us the pw-x that haibike is denying us buyers.

One Rebel 27.5 pw-x plus please.

And finally it takes a motor company to decide batteries should be standardized across brands. Way to go Yamaha!

I saw Pete Prebus' video from Interbike, and thought the BH guy must be misinformed when he mentioned 500Wh and 600Wh batteries. Here's hoping it's actually true.

The "thru axle" for the rear motor would also be interesting to see. The motor axle has always been hollow to accommodate the wire, but how does one thread the wire AND an axle through there? Sadly, from what I could tell, they're still using old-school QR skewers and dropouts on the front forks though. SHAME.

Of course, upgraded batteries wont be available for old bikes. The new (Evo/hub motor) bikes all use 48V motors, and thus wont be usable on 36V systems. The 2016 48V bikes might still have a chance, if the batteries still use the same form factor, saddles and connectors.

You're probably right about the battery incompatibility, however, there is hope, because a year or two ago, some Australian ebikers figured out that they could in fact use an American-spec 48V Easy Motion battery to make their 36V Aussie-spec Easy Motions go faster than 32kph. I believe they were able to hit ~45kph by using the 48v battery, which was a plug-and-play replacement (although I'm almost certain that Easy Motion would not recommend this!). I can't be sure, but I believe that it was the Neo Jumper or the Evo Jumper.

The 48V battery can also cause display glitching and possible motor overheating in hot weather.

Where the new 500Wh Bosch batteries are fully backwards compatible, the BH batteries are only partially, if even that.

I for one am not going to scrap my $3000 bike every three years just to get the newest battery, so this does represent a serious concern in the near future for most BH owners.

Hmm, interesting. How does the 48V battery cause anything to overheat? The bike's controller is pulling the same amount of current from the 48V battery as it would from a 36V battery. Current draw is responsible for heat in an electric bike battery or controller, not voltage. In general, increasing voltage is the best way to reduce heat in a battery or a controller, although this is often accomplished by a simultaneous reduction in current draw (e.g. more volts * less amps = same power output and less heat).

Let's just hope that BH will continue to sell replacement batteries for old models – fingers crossed! :D

Users have reported a boost in performance/torque with the 48V battery, so this would mean more watts produced by the motor, not just a higher RPM. 36 times 15A is 540W, and 48V times 15A would be 720W, which would be a 25% increase in power. The higher voltage also drives the motor with more RPM, hence the increased top speed. If the 500W /48V and 250/350W/36V Dapu motors weigh the same or are essentially the same motor, the 250W/360W motors should do fine at 48V.

I suppose an acute limiting factor would be the voltage rating of the capacitors in the controller. You could fry the controller before the motor.

I hope somebody with access to a Revo reports back with info as to the compatibility with Evo frames.

the front forks though. SHAME
The REVO jumper has thru axles.
The US counterparts have changed the specs and I saw two Revo jumpers with thru axle on it.

info as to the compatibility with Evo frames
While the dimensions are identical, the Revo can't accept 48V battery because the Brose system is designed for 36v only.

The Revo Lynx pro with 600Whr battery was one of the sleekest looking bike.

Thanks Ravi! If you get the chance, please try a Revo battery on a 2015 36V Evo (voltage should be printed on the battery and the hub motor shell).

If the battery shell and connectors are the same, it should work. Aside from the colors not matching the frame exactly, this would be a far better upgrade option for 36V (2015) Evo users.

Based on the video link above, am I right to assume no rebel lineup for the U.S.market? I sure would like to get my hands on a pwx Yamaha, just doesn't look like it is in the cards for us U.S. Buyers.

Court posted his video. Interesting details. New Evo batteries are built into an extruded aluminium case, so I suppose no backward compatibility (though the rep sorta skipped Courts question on that).

The new Dapu motors have a standard 12mm thru axle. I guess the skewer slips past the motor cable inside the hollow axle.

New center display still connects to the left hand display mount with a slave cable.

The Revo Lynx replaces the Evo Jumpers.

Be aware the new BH 48volt batteries may look exactly the same, but on close inspection, they have a tiny extra center pin on the connector (center of the 6 way diagnostic interface pins on the main battery connector) preventing them from being used on 36v Bikes or chargers. Mine is a South African model (EU spec) so perhaps USA is different. I guess they were trying to ensure the extra voltage/power doesn't change the 'classification' of the bike even though its limited by the controller (not that will stop anyone 'over-clocking it'). If you not aware and force the battery on the older bikes you will break it (just like we did). I don't really get why we can't use 48v batteries on the 2015/6 36v bikes as someone pointed out the controller sorts out the AC conversion anyway. I've seen 'Speed Hacks' incorporating an extra lithium pack in series with the 36v batteries and they seem works fine. The motor is a 350w limited to 250 (in some countries), so that should be no problem. The controller has a 36v sticker on it, but I'm sure it caters for over voltage. A fully charge 36v in around 41v nominal anyway. There is a firmware upgrade with a "disclaimer" going around, if you not botherd about compliance. It shouldn't impact on warranty as it just removes a firmware limit, maybe someone has the official take on this from BH.

I love my BH eBike, great build quality, I also love the speed and ride it flat our full boost everywhere (why not it's what eBikes were made for MAX FUN)

TOP TIP: when you are adjusting the power level on any BH bike, use your index finger under the panel to support the panel and you will have far less disconnect (error 13) issues
