    Yooniq 20-inch wheel bicycle

    If you're looking for a mini-velo and haven't seen it, check out http://respectcycles.com/p/bike .. horizontal drops would take an IGH easily.. you could install a disk fork if you wanted the braking power.. and it's a chromoly frame .. at sub $400 you'd have room to play .. also, unless the...

    Mid Drive with Internally Geared Hubs

    I have my road bikes geared so my preferred cadence ( 80 to 100 rpm) and resultant mph (cruising at 23 to 25 mph) closely match that of the max assist rpm of the mid-drive at the selected assist level .. so as I approach my target cadence in a particular gear or assist level, I approach a speed...

    Mid Drive with Internally Geared Hubs

    Most of the time, I just get my cadence close to the motor no load rpm and shift normally.. if you're running an inline amp meter, you can also glance at it and shift when amp draw is low (like 1 or 2 amps).. and shift normally .. but most of my riding is onroad, so a bit easier to keep cadence up..

    Mid Drive with Internally Geared Hubs

    You could use a commercially available gear sensor and program (assuming Bafang mid-drive) more or less delay and ramp up to suit your needs.. http://www.lectriccycles.com/gear-sensor/

    BBSxx tachometer?

    I use a cadence sensor .. with the BBS02, you have a max crank speed unloaded of around 110 rpm at full voltage .. keeping my cadence in and around 90 rpm and an eye to the amp reading on the display, I know if I am in an efficient motor rpm window.. more useful info on a display would always be...

    Fitting BBS02/BBSHD to a belt drive, the Priority Eight?

    Chainstay clearances at the final reduction housing on my three BBS02 builds range from the thickness of business card to about 5mm .. if one was absolutely sure they wanted a BBSxx series kit, buy it .. buy the Priority 8 .. mock it up in the frame like I did with the Moulton.. you'll clearly...

    Fitting BBS02/BBSHD to a belt drive, the Priority Eight?

    Biggest issue I see will most likely be the belt line.. doubt you can get the belt sprocket close enough to the seat tube to line up with the cog .. any Bafang adapter (104 110 130) will space the sprocket further away from the seat tube than the stock BBS02 chain ring.. I mocked up a BBS02 on a...

    Xnova 8kw rc middrive first test

    I've worked with 8mm pitch belts on bikes over the past few years.. one thing I found is that high belt tension isn't the answer for skipping at the small pulley.. I installed a snubber pulley to mount as close to the small pulley as possible to keep the belt from climbing off of the pulley...

    30 mile (each way) rail trail commute?

    Out of curiosity, what's your total km on the BBS01 that you use? what kind of issues? I'm doing 60km a couple of days a week and 30km most other days with a BBS02 road bike setup .. usually 30 to 35km/h average and 10 to 13 w/h per mile with a 12ah 52v battery.. right now, I'm in the ether...

    new cyclone 3000 w mid-drive kit?

    Thanks, I'm trying to get a handle on my own much lower powered bike without having a watt meter inline, and your figures help put it in perspective.. do you charge after your 8mi commute? if my rough figures are in the ball park you're depleting the battery around 6 or 7 amps? over the 16 or...

    new cyclone 3000 w mid-drive kit?

    Sounds like you've optimized your system.. what's your amp draw or watt reading at level road 32 mph ?

    Bike Racer - Motorpacing eBike Build - Feedback? (Q100@48v)

    There is the Hidden Power kit http://hiddenpower.eu/en/products/standard.html .. I have no experience with it other than they will drop the price substantially once you start communicating with them .. almost ordered two, but then decided to try a mid-drive first ..

    bbs02 steep hill best practices?

    Looking at the Breezer site, if your Nexus has an 18t cog as shown stock, then I would change it to a 22t or 23t (easy to do and dirt cheap, probably will have to add a link or two) .. that will drop your gear inches in 1st to under 30 .. that will make a big difference .. and your top gear...

    BAFANG power for the folding Montague for the airplane

    If going by the stock onboard 'battery graphic' indicator, I'm reasonably sure it will be fairly inaccurate because you are running a 52v pack as opposed to the 48v the Bafang 750w is expected to see.. A 'full charge' for your 52v pack would be 58.8v with shut off around 44.5v ... for a 48v...

    Full suspension mid-drive folding ebike, oh yEs!

    You make wonderful arguments .. but how to rationalize the Schlumpf SpeedDrive in my XP now.. and I really like the Thoroughbreds .. and then there's a Paratrooper hanging from the ceiling wanting electrification .. so many choices, so little time..

    Full suspension mid-drive folding ebike, oh yEs!

    You were lucky to get a Jetstream EX to use as a platform.. that model never made it to the US through Dahon retail channels . How has the German A front fork held up? How about the Dual Drive? any problems with the additional power of the motor kit? I've got an XP, and Dual Drives sitting...

    Full suspension mid-drive folding ebike, oh yEs!

    Speaking just for my Pacific Reach and the Airnimal Chameleon, the axle to crank measurement center to center is 16" .. which is the same as my Merlin.. so not overly short .. but my chain line isn't ideal.. I'm looking at a mostly straight chain line at cog 3 or 4 from the dropout of a 9 speed...

    Full suspension mid-drive folding ebike, oh yEs!

    Finishing up on my last folding bike project for awhile ... an Airnimal Chameleon with new Luna Shark 52v 13.5amp Panasonic battery and BBS02 motor.. 52t 11/32 running on 24" 520mm wheels .. only have around 100 miles on it, but I love it .. cruises along at 30mph pedaling at level 5 or 6 ...

    The Cadenza 8 would have been a great platform .. and with disc brakes too .. that was a good bike!

    Full suspension mid-drive folding ebike, oh yEs!

    I've hit 40mph on the flat, but wasn't trying for a top speed run yet ... mostly I enjoy pedaling in the mid 20's .. I'm putting together another system for an Airnimal Chameleon that will probably be faster top end as it runs on 520mm wheels with the same gearing as the Pacific Reach ...

    Full suspension mid-drive folding ebike, oh yEs!

    Hello folding bike enthusiasts! I'm new to e-bikes in general, but not new to folding bikes.. I've had one or more folders since 2004 .. the bike I chose for my first motor assist installation was a Pacific Reach Road which I've had in my garage for a few years not being ridden.. a degree of...
