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...

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...

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...

What do you mean? Wellgo pedals never have proper bearings to begin with :D They feel like there's steel shavings inside the races from new. I replaced mine after about 2000km with proper brand name platform pedals.

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...

Thanks J.R! Glad you found it useful. edit: Updated the instructions with optional Step 23, should your bolts seize or deform.

I've experienced the same thing in general, where US/UK companies no longer respond to email queries. Maybe it's how bike shops are more used to call in and walk in service, or the shops already know BH bikes are hard to service and just ignore anyone but their own clients. Sad to see many of...

Yes they did, and I've done about 900km with it over the summer. I love the extra speed, and have the fortune of safely using the full 32km/h about half way on each commute. 32km/h makes more sense for me, while still being safe. I only save about 12-15 min in my total time commuting each day...

The internal free wheel probably refers to the one-way bearing found in these geared hub motors, in either a pawl and ratchet or a clutch/roller design (that Dapu use). It allows the planetary reduction gear to disengage the axle when free wheeling forward. See this video.

To grt it right, you'd have to actually cross reference with another device, like GPS or Google maps measuring tool. See my posts here: https://electricbikereview.com/forums/threads/em-street-display-not-accurate-for-mileage.4404/

Every manufacturer has to come up with multiple enclosure designs to fit each application and to avoid infringement, so yours is different, but it still might be a Dapu. Could be a Dapu M155 CD for all we know, which is similar to the motor I have. Yours has no threat of balls falling into the...

..continued. Optional steps: Step 21. Using a rod punch tool to tap at the Allen bolts before trying to unscrew them. If they're really tight you might need to heat up the bolts with a heat gun or small torch. This will save you a lot of grief. Third hand optional. Use this method to open the...

Updated free hub overhaul guide: Since I have two motors and rear wheels, one of them just sitting in the corner, I thought I'd revisit the Dapu free hub overhaul procedure. DO NOT DROP BEARING BALLS INSIDE THE MOTOR! The magnets will suck them up and you'll never get them out. Step 1. To...

We haven't confirmed if this tool even works for the Dapu free hub yet, so please don't go ordering expensive tools yet. Maybe go to a shop and ask them to kindly try a few of theirs to see which size you've got, or ask the online seller for accurate measurements. I've no experience with the...

Sorry to hear you (and us all) being left helpless with an expensive product one would expect to get decent support for. Me and KeiKei (another user here on the forum) have been researching the Dapu freehub, and he recons this tool "SuperB TB-1018" is the one to open the cone bearing. I made a...

The way I calibrated my display was I used the Google Maps (desktop) measuring tool to plot and measure the route that I usually take to commute, then by riding it a couple times, find the wheel size that best matches the trip meter to the actual distance. The software on my display is way off...

I'll be dismantling my Euro Evo 29er wheel at some point, as I want to get rid of the cheapo Alex DM18 rims for good. I was annoyed by the lack of readily available spare spokes or rims from BH as soon as I bought my bike, and in the end I'm far better off without needing their spares at all...

It is noticeable to me. From a stand still it's slightly more sluggish, but then again I've had 1.5 years of experience with the stock motor.

Thanks for posting bjornb! I've seen pictures of those on Neos, but yours is the first Evo. I suppose, eventually somebody could try modifying a Nitro battery to reduce the voltage to around 43V to achieve the same results. But you'd need a charger with matching voltage. Your setup has extra...

Here she is, all laced up nice like. A local bike expert did the wheel building. We chose Sapim Strong spokes, which aren't 13G (2,3mm) all the way like the original spokes, but just the bend and a couple inches above it is 13G, the rest is 14G. I would have wanted 13G spokes of course, since...
