    New wheel size?

    There has been some press in the bike world recently about a new wheel standard that was developed by WTB and recently showcased at the made bike show in Portland by Moots of Steamboat Springs, CO that have been making Ti bikes for decades now. It has spawned quite a bit of angst amongst the...

    Ultra Tuning: Decoding the Voltage Section of Torque Tab

    I admit that there is some head scratching that needs to go into tuning an M620 for your needs. Before Smorgasboard took the time to understand the parameters and lay down the facts that he came up with and shared here it was really a catch as catch can deal sorting through a bunch of other...

    10 miles with a 36 volt 10 AH battery.

    33v is way below the low voltage cutoff for a 48v battery. Your max of 42v is closer to the LVC in fact? Are you sure it is a 48v system? Using only 250w for 23+ mph is pretty frugal but if you say so.....

    Currie Electrodrive Compatible Bike Lights

    Without knowing the input/output and connections available on your specific bike it would be hard to recommend something compatible. The manufacturer should be able to provide those and from there you can get a better idea of what is available on the market. I would suppose there are going to be...

    10 miles with a 36 volt 10 AH battery.

    Calculates to 36wn/mi which is on the high end but so many factors to consider such as overall weight/tire psi/road surface but I would say that trying to maintain 20mph is the biggest factor even in a low assist level? If you were going even faster it draws even more wh's/mi. I don't think...

    Do Bosch motors add resistance at the class 1/3 support limit?

    Undo the chain and spin the cranks. If there is some resistance felt that is part of the effect you are feeling along with the added system weight over your meat bike. Brose are known for their relative lack of resistance in the final drive due to the use of an internal belt rather than gears...

    Bafang G020 hub motor — conflicting specs

    According to the label shown it is a 48v system. In order to figure out the true peak watt output you need to know what Amp your controller is set to, V x A = Watts. Usually controllers on bikes like yours are set at 15A but could be as high as 20A. The 250 nominal is just a work around EU...

    Is Sondors next?

    Never thought that the $500 fat bike would be delivered so no surprise here. Amazed Sondors had the run it did, as well as the amount of faithful it gathered. PT Barnum was so prescient. Every day now getting emails about some brands heavily discounting their bikes or at least some models...

    Little clear cut action up on the hill. The perpetrator Almost ready for replanting As sad as this looks it is actually a sustainable forest management method here in the PNW. The timber is destined to become 2x's down on the valley floor, the slash piles will house critters and...

    Try cleaning and lubing the cable/housing as well as possible.

    Vok Quadracycle

    It is more a last mile solution for delivery purposes. In fact NY State is in the process of adjusting their "bicycle" law to allow for 48" wide/4 wheel pedal assist vehicles such as this UPS rig. Currently it is 36" wide/3 wheel for use in bike lanes.

    Gazelle T9 chain drop

    Can be as simple as a stiff link in the chain or a bent tooth on the chain ring. Might be worth a visit to this site to see if anything there is relatable? https://wickwerks.com/chain-suck/

    OK to feather my thumb throttle?

    An electronic throttle is not unlike a simple household dimmer switch. However there are parameters that can allow it's sensitivity via voltage to be adjusted via the controller but if you can't access them via programming with the model of bike/controller you have then you just have to adjust...

    Bafang Motor's Waterproof Rating?

    I drowned my M620 via total immersion like a dumba#@. It eventually ended up ruining the motor although I tried to dry it out afterwords. It gradually lost power over the next few weks and then it died. Before that time it had been ridden in wet conditions here in OR and washed after riding with...

    They are basically a hybrid blackberry that is more plump and sweeter. I used to live near a commercial patch that allowed U pick and where I got hooked on them. A friend has them growing in his green house north of me also that I get some from. I divorced the pie maker, now more of a crumble type.
