    Todestrieb vs Psycho rims?

    I noticed a rave on a bike polo blog about the ruggedness of a 32mm wide (outside) 600 gm (don't know if the weight is for the 26" or 700C size) Todestreib 36h rim. The Todestreib is either 25% or 33% lighter than the similarly shaped Velocity Psycho 31.5mm wide which weighs 800 gm in 26" and...

    ebike friendly Stone Brewery

    Yesterday I took a 45 mile bike ride after I determined that the Stone Brewery in Escondido, Ca. was very EV friendly. It seems that ownership and senior management have plug-in electric cars which motivated the brewery to install a pair of free-to-customers charging stations in front of the...

    102V DC to 12V DC converters

    All DC to DC converters I've seen on ES seem to peak at a nominal input voltage of no more than 72V. I am powering an ebike with a 32S 15Ah Headway LiFePO4 battery pack. Nominal output is 3.2V x 32 cells = 102.4V and peak output is 3.55V * 32 cells = 113.6V. (cell balancers bleed off...

    What's Happening with Golden Motors USA?

    I noticed that the website for this entity in Arizona no longer works. It previously was run by the same people who own Arizonaebikes. I also note that San Diego Electric Bike asserts: "Distributor changes are in progress in Scottsdale." Anybody know more?

    cell man A123 Triangle Packs & Bags resold by SD Ebikes?

    I noted that Patrick Winston at San Diego Ebikes now stocks and offers 11.5A 16S5P A123 triangle packs as well as large triangle battery bags. I wonder if he imports directly from Cellman as I am aware of no other source. http://www.sdelectricbike.com/A123_BATTERY.html

    Battery mounted on front suspension rack--Thoughts?

    If I were to split a 72V 16AH Headway pack evenly on both sides of a front suspension fork would stability suffer or would steering quickness merely slow down? The 24S 40160 cells in the pack would weigh 0.5kg each so the total pack would weigh 12 kg plus bms plus mounting hardware and...

    HS3540+front Surly Pugsley 135mm cromo fork & Suspensn Stem?

    This combo might be gentle on the wrists for a gutsy fwd commuter. Has anyone used the suspension stem riser with 20mm of travel? Does the suspension stem create any handling issues. http://www.jensonusa.com/store/product/FK282C00-Surly+Pugsley+Fork+135Mm+Spacing.aspx...

    What is a 4 wheel electric device that can't exceed 20mph?

    What is a 4-wheel drive electric vehicle that meets the all the characteristics of Federal law 107-319 except that it doesn't have just 2 or 3 wheels? From what I've read, most state laws describing electric bicycles adhere to the Federal 107-319 definition which describes the "device" as...

    Is Pusher Trailer hitch Regen Safe?

    Would a BOB trailer hitch attached to either a motorized BOB or a motorized bike frame pusher with a 24" hub motor have any performance or stress issues with regen? I would think that the pull on the BOB NUTZ would be less stressful to the bike's rear dropout area than a regen rear bike wheel...

    Trying to find an oversized ( 1 1/18) bike stem ?

    Do you really mean 1 1/18 or 1 1/8? For my impending build I'm planning I expect to increase upright riding position flexibility by using both a 3.5" Nashbar stem extender and a 125mm Delta stem that is adjustable from 0 to 45 degrees. They can be found on Nashbar as adustable 125mm long 0-45...

    California 20mph ebike vs 30mph moped alternative pros & con

    I've searched and read that California requires no drivers license to ride a 20mph ebike but requires a one-time only $18 moped license plate fee for either an electric powered or gas powered moped (with or without pedals). Permission to ride a moped requires either a M1 motorcycle code on your...

    Clyte HS2440 & 72V 40A controller for BOB Pusher?

    Most BOB pushers I researched either use sprocket driven external motors or weld longer replacement forks to accomodate larger than 16" diameter wheels. I've wondered what simple Hub motor conversion with adequate speed can be done effectively on a stock BOB Yak. Looking at the ebikes.ca...
