You will not believe the weight saving possible by changing your stock eBike wheels to a set of our BF/eBs. This weight saving increases acceleration and battery life and when combined with the extra stiffness of our rims gives incredible handling advantages, boosting the agility of your bike. Choose from 31mm or 35mm internal width rims. 

For comparrison, the standard 27.5 wheelset on one of our customers £5100 Whyte E-160 S weighed his wheels at 3100g, compared to the same width and stiffer 27.5 BF/eB 37/31s he replaced them with at 1850g. 1.25KG of rotating mass saved!

Choice from our BF37/31 or BF42/35 rims with eBike proven Hope hubs and upgraded spokes on the rear wheel.

We have sold lots of standard BF37/31 and BF42/35 wheelsets to eBike owners over the past few years. We always recommended Hope hubs as Hope themselves build eBike wheels on their Pro4s. We knew that our standard rims would be more than up to the job and this has been proven in that we haven’t had a single damaged rim – we are so confident we offer free lifetime crash replacement with every wheelset. 

The only feedback we received suggesting any improvements to the wheels for eBike use was that one customer snapped a souple or rear spokes due to the increased torque put through the rear wheel along with the increased weight of the bike. We have addressed this by building our rear eBike wheels with Sapim Strong spokes with 32% more material around the hooked elbows and and 23% extra along the centre section. 

Front wheels are built with Sapim Race spokes with the same circular profile as the Sapim Strong to keep the wheelsets as light as possible. 

Please refer to our BF37/31 (31mm internal width) and BF42/35 (35mm internal width) product pages for further information about these wheelsets.

    Mark owen

    eBike customer
    As a returning customer I had high expectation. I purchased a Spesh Turbo Levo but found the wheels so heavy to get around tight berms and alternate left – rights felt like riding an oil tanker
    The wheels I’d bought previous had been the best wheels I’d had in twenty five years and at a twenty stone rider they’ve seen some abuse
    Especially on the welsh black runs! So it was going to be no surprise that the wheels were going to live up to the abuse
    But not only just weight saving and handling
    Along with better braking these wheels have given an increase in power saving to the battery.
    I must get at least five miles extra for the same speeds and effort (15% gain)
    Nine months and 2000 miles wheels still run true although the extra torque have broken some spokes at the J bend cassette side (mine have standard CX Ray spokes and were built before these eBike specific wheels with the stronger spokes were available, plus as I said before, I’m a twenty stone plus rider) quick and easy to fix with a spare spoke or two and haven’t even needed truing up.
    That’s the only improvement I’d make it I had a new set – stronger spokes on the rear wheel to handle the 250watt 90nm motor plus what I can put through the back wheel!

    Great wheels thanks
    Look the dogs too

    Well had the Levo stollen what a bummer
    Tried the normal bike again but it’s hard to go back so purchased another ebike
    First thing I upgraded was wheels with another pair of blue flows finest

    This time with the heavier duty spokes on the rear wheel and the DX driver to stop the cassette eating the cassette body.
    Wow what a difference again
    This time three pounds of rotational mass saved (2.35kg)

    It’s now faster, sharper turning – switchbacks and left right berm combos are like a normal bike
    I’m getting air – on an ebike
    It stops quicker, and I’ve reduced damping on the suspension – so much more traction from the unstrung weight

    You can think with an ebike that it doesn’t matter as the power of the motor will compensate for wheel weight – think again it’s transformed a great bike into an amazing bike
    The best upgrade you will ever make

    For those who watch “fast and loud” this won’t be lost
    “Get you some of that”

    Thanks again Stu for another great pair of wheels -indestructible performance at the price of one enve rim
    And I’d challenge anyone to prove there’s a difference in quality
    ( bike is whyte e160s )
