    Zen Photon Ultra - limited version (Bafang Ultra, Rohloff Speed hub, Gates belt drive)

    The Bafang Ultra is also known as the M620 and to add further confusion the G510. The motor is able to be speced with either a 48v or 52v controller which would make for different peak watt ratings as well.

    Rebuilding My Gen 1 Hydra Fatty

    I am confused? Even if your motor controller is rated for 2300w can't you still use lower assist levels to get more range and less drivetrain wear? The 52 and 48v 21700 cell batteries I had made with a 40A BMS are only 15ah due to size restrictions using a stock case for the e22 Dengfu frame...

    Any way to add a front or rear wheel motor to a thru-axle boost bike?

    You might find that Grin, if you follow the link above, has at least another option for a hub solution? I believe one is also a geared version so that gives you the available spectrum to choose from. I have had the All Axle front version since its Beta days and it works very well and as you...

    Yamaha Leaving US Market

    Doesn't surprise me. But they only mention the U.S. market so I assume that the EU, Japanese and Asian markets as well as others are still a go? If one goes to their regional sites their product line expands quite a bit over what they made available here. Also will they still sell motors to...

    Odd Japanese domestic ebike

    The motor looks like the original Yamaha motor that they brought to the Japanese market 30yrs ago. At that time 24v SLA batteries were in use and were upgraded to 36v NiMH or LifePo4 type cells as the concept of ebikes matured. It wouldn't surprise me that the motor would be able to withstand...

    Need your help: Left side motor cover question

    Assuming the area shown is the only one that is broken just fill the hole with silicone and it will glue it in place. Will at least help until you can get a replacement. When you do get it you can just peel out the silicone. You might want to back off on the other attachment bolts and do as...

    Yamaha YDX-Moro 07 Special Edition for $1600

    This post makes all kinds of sense. The Medford deal was an outlier for sure and kudos to those that were able to take advantage of it. Yamaha dumping inventory at the end of the season basically factory direct because they have so few IBD dealers also makes sense for them going forward into the...

    Do we have a Franken bike thread?

    This was ugly but effective BITD before batteries made the leap to being efficient.

    Yamaha YDX-Moro 07 Special Edition for $1600

    Yeah for years you could show OR residency via a drivers license and avoid paying tax in WA but that hasn't been the case for a number of years now. We used to take good advantage of it coming back from AK in the fall at LFS and REI! Both Vancouvers take advantage of being close to borders for...

    Greetings from a new member in...Zambia

    You should be as well protected as possible with the tire liners and slimed tubes. Sounds like punctures are inevitable there and the best you can do is to stop them from leaking ASAP. I have had really good luck with going to tubeless to combat punctures but where I live there aren't alot of...

    Thoughts on Vvolt ebikes?

    This came across my screen today, new model from Vvolt: https://vvolt.com/collections/ebikes/products/centauri-ii 3spd auto shift/belt drive and Ananda Class III mid motor with a UL battery seem to be solid sale points for the commuter set. Portland, OR based.

    Yamaha YDX-Moro 07 Special Edition for $1600

    I live in Northern OR as opposed to where the OP lives and when I got to checkout an 07, not the 30th edition. was quoted as $2800. Part of that was the $280 in tax applied because the participating dealer closest to me is in Vancouver, WA and WA has sales tax. But still doesn't account for why...

    Is Any E-Bike With A Throttle A Type 2 E-Bike?

    "I expect swift consequences to legislators" The legislators that dreamed this up need a swift something to a certain part of the human anatomy. As fast as the wheels of gov't can go implementing regulations it takes forever to get them to annul any so I don't hold much hope other than it never...

    People for Bikes: Progress on Ebike Laws in the US

    "reclassified into the moped category with all the accompanying retrograde baleful implications for rider safety." MoPed's require DOT approved rims/tires, full lighting consisting of head. tail, turn signals and brake, horn and mirrors, an automatic transmission and a VIN # and need to be...

    Bafang Ultra, new (quiet) steel gears, Canbus Calibration with the K1-Flash worked great!

    Now you will have to start ribbing him to get an IGH eh?

    Yamaha battery seems difficult to source and is a tad expensive....

    I saw YT tests by Electric Bike Report of the Cross Core and the Wabash RT that have the ST Class 3 motor and they reported a range of 105 and 115 miles respectively with the 500wh battery. I believe they used the auto feature and the area they were in looked like somewhere in the SW that...

    Is Any E-Bike With A Throttle A Type 2 E-Bike?

    It certainly is for this model? As well as a few of the others I saw on their site. https://mondaymotorbikes.com/products/piezo The Utah law seems to represent what PFB was lobbying for in CA. but they didn't bite. Thanks for the fine print explanation m@ because that definitely puts a...

    Is Any E-Bike With A Throttle A Type 2 E-Bike?

    More Gov't throwing the baby out with the bathwater logic. This statement from PFB says what the problem really is: PeopleForBikes, which has worked on behalf of the industry in the writing and amending of the bill, opposed altering the class definition. The group said the legislation could...
