Not a spectacular ride but I want to do more of the Palouse to Cascades (John Wayne) trail in WA. East of the Columbia River goatheads are reported to be a problem. I have Schwalbe G-one tires with tubes and Mr Tuffy liners. Wheels are tubeless ready and I picked up some Orange Seal, went to...

I want to do a train and ride this fall but "Amtrak accepts electric bikes and scooters powered by lithium-ion batteries and certified by a nationally recognized testing laboratory". My Yamaha batteries aren't UL certified nor are the batteries for my Qiroll or Tongsheng kits. Ryobi and...

Short research letter. The large year over increases in injury attributed to ebike use are notable and may or may not catch the attention of the public and authorities thus prompting increased regulatory action...

From reading some posts I had the impression that ebikes cannot be shipped without special hazmat certification which consumers cannot obtain. My impression was incorrect, at least for shipments within the contiguous USA. As an aside I have used bikeflights to ship a standard bicycle, it was a...

Bottom right corner connector in the image. Can anyone tell me the center to center distance between the posts? Length, width and height of the posts? Thanks for any info.

I'm hoping to ride around Crater Lake again in 1-2 weeks during the "ride the rim" east road closures. Last year I rode around it 3x on closure and non-closure days with a TSDZ2 equipped Walmart Schwinn Avenue hybrid. This year I'm planning on bringing my BH (Yamaha) gravel bike and this...

A ride to not miss, Sept 9 and 16th this year. I've done it 4 times, only once with an ebike last year. When I first did this ride several years ago I saw no ebikes, few years ago (pre-COVID before the ride was cancelled for a couple yrs) only saw one couple on ebikes, last year a majority of...

Tire has around 2000 miles on it and has been rotated, never run above 70psi which is the listed max. Was on the back, tire currently on the front looks OK. Mostly paved street miles but also ridden on coarse gravel. The knobs aren't worn that bad but the total thickness of the rubber...

I'd never heard of them until they were mentioned by a member on EBR. I bought a couple flavors, the ones with 40mg of caffeine. They are nasty tasting but give a boost when I need it. Anyone else tried them, if so what do you think?

I've ridden over 90 miles and it is still over 50v. Fully charged it 3-4 weeks ago then rode 50 miles on the Olympic discovery trail, let it sit a couple weeks then rode again yesterday and today another 40+ miles. Probably in the neighborhood of 4,500 ft of climbing total. Still over 50v...

This motor is being sold on ebay nicely laced into a decent looking rim. They are apparently from a defunct bike share, Jump bikes, new/unused. I bought one last year without a real plan for it and a few days ago did a test installation in my 26" Dahon Jack folder. I think it works really...

Saturdays Sept 10 and 17. They close the east rim road to motor vehicles until 6pm I've done this ride a few times on regular non-assist bikes and it is not to be missed. I've met people from Europe who came over for it. Ebikes allowed but no throttles - it's a hike/bike event not a motor...

I like my BH gravel X with PW-SE motor but a major flaw is the walk assist is disabled, as on some other brands of bikes that use the Yamaha drive. I've searched the internet in vain to find a solution. It seems that Yamaha and others have implied that it is a firmware programming issue due to...

This coming Sunday is a ride event in Olympic NP. Hurricane road closed to car traffic 7am to noon for a sponsored bike ride. Ebikes can't register but I doubt that non-registered riders are prohibited by the national park. I've done this ride on non-event days a few times on regular...

Put off by all of the bickering/politicizing and other random nonsense posted over and over by the same knuckleheads and self proclaimed experts on EBR - and just want to ride? Check out the La Grande Parks and Rec sponsored and supported 1 or 2 day 134 mile Grande Tour Scenic Bikeway ride...

I've driven and motorcycled going to the sun road in Glacier NP a few times but never biked it. Starting June 14 there are restrictions on biking so I reserved a campsite at Apgar for 5 days a bit over a week prior to when the restrictions set in. Should be able to ride to near Logan Pass by...

I have a heavy 48v 10ah LiFePO4 battery that I don't have a use for. Except that I also have a 12v Minn Kota 38lb thrust trolling motor that I could use with a kayak for fishing but my old lead acid deep cycle battery weighs over 65 back breaking - kayak sinking pounds. The 10ish# lithium...

I just mounted a 26x1.75 Tannus Razorblade airless tire on a geared rear hub motor rim. It was much more difficult than the videos showing mounting of narrow 700c versions. Here is a video that I found that was more realistic for the tire that I mounted. Looking forward to riding this bike...
